Add support of Jabra headsets via the hidapi library.
Add support for two Jabra headset models (Engage 55 & Evolve 2 55), to handle the calls directly from the headset. The supported actions are:
- Answer an incoming call
- Hang up the current call
- Mute/unmute the microphone
- Put a call on hold / resume it
- Reject an incoming call
- Switch between two calls
