Add basic Channels integration (#1407)

* Update dependencies

Add Channels optional dependency and an Extra package for channels

* Add documentation for Channels integration

* Add implementation for basic Channels integration

Complete implementation for websockets, partial implementation for HTTP (multipart/form-data still pending)

* Add unit tests for Channels integration

These unit tests are mostly copied over from FastAPI, and certainly aren't comprehensive or covering all the Channels-specific cases. However, they provide a reasonably good level of coverage for actual protocol behaviour.

The HTTP consumer does not yet have any unit tests.
