1. build https://github.com/signalapp/ringrtc
   1. set max_bitrate_bps in https://github.com/signalapp/ringrtc/blob/653757074949f48ff1e4c1490550932cea3276ea/src/rust/src/webrtc/media.rs
2. somehow put binary into https://github.com/signalapp/signal-ringrtc-node/commits/master/build/linux/libringrtc.node
3. use custom signal-ringrtc-node in signal-desktop
