feat: introduce Message, Serializer, Deserializer and Binding interfaces (#324)
* lib(messages): Implement a 4.0 Messages and other supporting interfaces

This commit introduces the Message, Serializer and Deserializer, and Binding
interfaces used to convert a CloudEvent into a Message that can be sent across
a transport protocol. The first protocol implemented for this is HTTP, and some
of the functionality formerly in src/transport/http has been simplified,
reduced and/or moved to /src/messages/http.

Test for V1 and V3 events are in place. Conformance tests have been modified to use
these new interfaces vs. the HTTP Receiver class.

test: implement pending tests leftover from TS rewrite (#315)
This commit implements 4 of the 6 pending tests that were not completed
during the TypeScript rewrite. The two tests that were not implemented
were (one for each of v1 and v03):

```
it("returns a JSON string even if format is invalid");
```

I don't really know what that's supposed to be/mean, so I removed them.

fix: ensure that data encoded as base64 is parsed as an object (#285)
The 0.3 specification states that `datacontentencoding` may be set to base64.
If an incoming event arrives over HTTP with this value set, and the content type
is either application/json or application/cloudevents+json, then ensure that

BREAKING CHANGE(lib): rewrite in TypeScript (#226)
This is a major rewrite of the entire codebase into TypeScript. Nearly
all tests have been retained except where behavior is significantly
different. Some highlights of these changes:

* lowercase all CloudEvent properties and fix base64 encoded data

Previously there was a format() function that would convert a CloudEvent
object into JSON with all of the properties lowercased. With this rewrite
a CloudEvent object can be converted to JSON simply with JSON.stringify().

However, in order to be compliant with the JSON representation outlined in
the spec here https://github.com/cloudevents/spec/blob/v1.0/json-format.md
all of the event properties must be all lowercase.

* lib(transport): make transport mode an Enum
* src: allow custom headers (#1)
* lib(exports): export explicitly versioned names where appropriate
* lib(cloudevent): modify ctor to accept extensions inline
* lib(cloudevent): make extensions a part of the event object
* test: convert all tests to typescript
* examples: update all examples with latest API changes
* docs: update README with latest API changes
* src: add prettier for code style and fix a lot of linting errors
* lib: move data decoding to occur within the CloudEvent object

fix: introduce CloudEventV1 and CloudEventV03 interfaces (#194)
This extracts all of the attributes from a `CloudEventVX` that
are not generated by the constructor (id and specversion) into their
own `CloudEventVXAttributes` interface which the `CloudEventVX`
interface extends. This allows TS devs to optionally provide `id`
and `specversion` with proper autocompletion.

Additionally, I have added a union type, `CE` in `cloudevent.ts` which
represents any of `CloudEventV1`, `CloudEventv03`, `CloudEventV1Attributes`
and `CloudEventV03Attributes` interfaces.

Finally, this commit changes all of the user facing API to be `.ts` instead
of `.js` files.

The existing documentation in `./docs` was removed. It should be replaced with generated
HTML from tsdocs, pending some other method of publishing API documentation. That will
come as a separate, docs-only PR.

const event = new CloudEvent({
  source: 'http://my.event.source',

// get and set all properties standard property notation

lib!: refactor HTTP bindings and specifications (#165)
This is a breaking change.

This commit makes a number of changes to the HTTP bindings code in an attempt
to simplify its usage and implementation. From a very high level, this inverts
the existing dependencies.

As an example, consider `lib/bindings/http/receiver_structured_1.js`.
https://github.com/cloudevents/sdk-javascript/blob/v1.0.0/lib/bindings/http/receiver_structured_0_3.js

This class instantiates `lib/bindings/http/receiver_structured.js` and delegates
its function invokations to it. This had the effect of requiring a user to know what
event versions they would be receiving. And for me personally was a little confusing
as a maintainer.

The change introduced here reverses that logic, so that the version agnostic receiver
is what the user instantiates. It instantiates the approrpiate version of a specific
receiever and delegates to it - reversing the dependencies.

I've also moved all of the top level directories related to HTTP versions into
`lib/bindings/http/v1` and `lib/bindings/http/v03` and generally done some rearranging
to make the repository structure cleaner and more organized.

lib: expose constants as a top-level export (#161)
This commit pulls the constants up from the lib/bindings/http/constants.js
and exports them in the top level index.js. There are some elements of the API
where we expect users to provide constant values, and this makes it easier for
them to be sure the values they provide are what is expected.

I've also added two new constants: `BINARY` and `STRUCTURED`.

feat!: expose a version agnostic event emitter (#141)
* feat!: expose a version agnostic event emitter

This is a breaking change.

This commit exposes an HTTP based event emitter that simplifes the API.
To use it, simply import the SDK and start emitting. The default spec
version is 1.0, but you can use 0.3 by supplying that to the constructor.

By default, CloudEvents are emitted in binary mode, but this can be changed
by providing the "structured" parameter to the `send()` function.

This commit also eliminates the version specific emitters and receivers
from the `v1` and `v03` exports, and eliminates the explicit usage of
versioned emitters from `lib/bindings/http`.

Finally, the CE headers can be retrieved from the emitter for a given
event by passing the event to the `headers()` function.

fix: ensure binary events can handle no content-type header (#134)
* fix: ensure binary events can handle no content-type header

The fix provided in https://github.com/cloudevents/sdk-javascript/pull/118
only included tests for `receiver.check()`, and the change in that
case was to add the `application/json` content type to the cleansed
headers if to type was specified.

However, `receiver.parse()` did not receive the benefit of this change. It
calls `this.check()` but then sanitizes the original headers again, and the
missing content-type was not re-inserted into the newly sanitized headers.

This commit, modifies the code so that `receiver.check()` does not insert
the content-type, but does allow the validation check to pass if no
content-type header exists. When `receiver.parse()` is called, and the
headers are sanitized again - and this time used to look up parser implementation,
the default `application/json` content-is applied if no content-type header
exists.

I've also removed a redundant call to `receiver.check()` in receiver_binary_1.js
and simplified the usage of `Constants` in the test.

feat: expose a mode and version agnostic event receiver (#120)
Event receivers in the wild may not always know what version or mode an
incoming event is. Instead of requiring developers to inspect the headers
themselves, the SDK should provide an HTTP receiver that is capable of
figuring out what the version and mode (structured/binary) of an incoming
event is and handle it appropriately.

In determining the best way to expose this, I chose to modify the API a
little bit. Now, instead of `const CloudEvent = require('cloudevents-sdk');`
users need to destructure it.

```js
const { HTTPReceiver, CloudEvent } = require('cloudevents-sdk');
```

This change should not be backported to 1.x.
