For browsers that don't support headerBytesSent in RTCOutboundRtpStreamStats
neither headerBytesReceived in RTCInboundRtpStreamStats, we are now able
to calculate upload and download rates.
We are also able to get transportStats information for browsers that

Using getStats api and peer information to retrieve upload/download rates

Should fix an issue with the recent Chrome 92 intervention that limits
the number of concurrent WebMediaPlayers (an inner element of

generated a skewed accounting of WebMediaPlayers in the session.

When mic is locked, user is not able to talk so it doesn't make sense
