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
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.

This change adds a `ValidationError` type that extends `TypeError`. Any time a `CloudEvent` cannot be received and created with the given input, this error will be thrown. Tests have all
been updated to check for the error type.

This commit removes the require of uuid from this test and uses a
hardcoded value for the 'id' constant instead.
The motivation for this is that the value for 'id' does not need to be
generated for each test run, and fewer requires helps readabilitly I
find.

This commit changes the event mode detection in `HTTPReceiver` so that it will
throw a TypeError if the event mode can't be detected per the spec.

* 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.

* chore: clean up header sniffing

This commit removes the unnecessary use of Promises in the 0.3 unmarshaller.
There was actually no asynchronous activity happening in that function, so
there was no need to deal with Promises, and as a result testing was made
much more difficult.

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.

Enforce the use of `let` and `const` by using elsint rules.
When creating the eslint configuration, I had assumed that
`extends: eslint:recommended` would have covered this, but
apparently not!
Existing usage of `var` fixed with `npm run lint -- --fix`.

This commit removes support for the v0.2 specification. It also removes the
`contenttype` attribute from the `CloudEvent` object. While the HTTP protocol
binding specifies that in binary mode, the `datacontenttype` attribute should
map to the HTTP Content-Type header, that doesn't mean that the `CloudEvent`
object should have a `contenttype` property.

This commit updates all of the dependencies in package.json to
their most recent versions. It also removes dependencies that were
specified in package.json but not used - or only used in a
`require()` statement.
These changes have some ripple effects. Istanbul has not been
supported for some time, so it has been replaced with nyc.
The code coverage reporting tool from codacy has been updated
as well. This could not be tested without having the API token.
Finally, the CI job has been modified to run tests on Node.js
versions 10x and 12x. All older versions of Node.js are no longer
maintained.

This commit modifies both of the 1.0 emitters so that they may
accept typed objects as a part of the configuration. When using
mTLS in Node, you need to provide an `Agent` to the underlying
HTTP handler. In this case, Axios will pass this object along to
Node.js when it is provided.
