py-daphne: updated to 2.2.0

2.2.0:

* HTTP timeouts have been removed by default, as they were only needed
  with ASGI/Channels 1. You can re-enable them with the --http-timeout
  argument to Daphne.

* Occasional errors on application timeout for non-fully-opened sockets
  and for trying to read closed requests under high load are fixed.

* X-Forwarded-For headers are now correctly decoded in all environments
  and no longer have unicode matching issues.
