RTCDataChannelStats: type property

The type property of the RTCDataChannelStats dictionary is a string with the value "data-channel".

Different statistics are obtained by iterating the RTCStatsReport object returned by a call to RTCPeerConnection.getStats(). The type indicates the set of statistics available through the object in a particular iteration step. A value of "data-channel" indicates that the statistics available in the current step are those defined in RTCDataChannelStats.
