The crash occurs every time the audio track is muted/unmuted, if the emitter fails to initialize
("Failed to start VADAudioAnalyser" warning is
printed).

On Firefox it throws:
DOMException: AudioContext.createMediaStreamSource: Connecting AudioNodes from AudioContexts with different sample-rate is currently not supported.

* feat: use getSynchronizationSources on the receiver for remote audio levels
Use getSynchronizationSources if it is supported, fallback to using getStats otherwise.
* feat/ref: Use the local audio levels from LocalStatsCollector
When using getSynchronizationSources, use the audio levels from LocalStatsCollector for NoAudioSignalDetection.js
Remove obsolete code - TalkMutedDetection feature using audio levels is not used anymore

* feat: implement vad noise detection

* start detection services on initial track add

* additional refactor / calibrate noise detection

* stop detection services on track remove

* address code review

* address code review p2
