is not support latest implementation

[fanlion]

The current Chrome implementation is RTCPeerConnection.getStats with info here: https://www.chromestatus.com/feature/5665052275245056

Mozilla uses the RTCStatsReport interface that provides a variety of RTC connection information and is documented here: https://developer.mozilla.org/en-US/docs/Web/API/RTCStatsReport

I find this is now good ideal. but I convert stand getStats to be google's Stats.and don't have video brew and too much unuseless info.I suggest to close it
