v0.4.6

• fire_and_forget now only removes the stream id when the future denoting the frame was sent, is done
• API documentation auto generated at rsocket.readthedocs.io
• Request router changes:
  • Raise error on empty or None route specified in request router
  • Added the following methods to RequestRouter to allow specifying handlers of unknown routes:
    • response_unknown
    • stream_unknown
    • channel_unknown
    • fire_and_forget_unknown
    • metadata_push_unknown
  • Officially support route aliases by using the decorator multiple times on the same method
  • Fix value mapping in request router:
    -A parameter of any name (not just payload) specified on a routed method with a type-hint other than Payload will use the payload_mapper to decode the value
