WebRTC rework

Browse Source 
Only using two sinks and swapping between them
Reworked the device rotation logic as it didn't work well with pitch ( you could tip the device front to back and the rotation went out of whack, so had to resort to more robust calculation for the device orientation.
Had to use a deprecated sensor setting but it's the only one I could use that works.
