Channels integration

[WisdomPill]

Hello!

As all the other people that thought that the base repository was dead, I started working on my own version of the library, especially I found myself working on an integration with channels so that the same client is authenticated for web sockets too through cookies.

In short, I made a middleware that authenticates looking for the cookie with the jwt token since web sockets don't support headers (as far as I know).

Would you be interested in merging that feature?

I would be glad to use a library that has more contributors and to help of course.

@WisdomPill I'd love to merge this feature. Feel free to send a PR with the middleware class and some test cases. You can assign it to me.
