  - implement muting tracks with m.call.sdp_stream_metadata_changed
  - implement renegotiation
  - making logging better
- - finish session id support
+ - DONE: finish session id support
     - call peers are essentially identified by (userid, deviceid, sessionid). If see a new session id, we first disconnect from the current member so we're ready to connect with a clean slate again (in a member event, also in to_device? no harm I suppose, given olm encryption ensures you can't spoof the deviceid).
  - implement to_device messages arriving before m.call(.member) state event
  - reeable crypto & implement fetching olm keys before sending encrypted signalling message
