* 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 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.
