Add Lyra voice codec (3 kbit/s)
Google has announced a low bitrate speech codec, lyra, which aims to encode speech with 3 kbit/s: https://github.com/google/lyra/
With release 0.2, it seems to be fully open source (https://github.com/google/lyra/releases/tag/v0.0.2). Maybe it could be implemented int Jami to save bandwith and prevent connection issues with voice only calls?
