  // webrtc-pc 20171130

    5.2.  RTCRtpSender Interface
      getStats
        1.  Let selector be the RTCRtpSender object on which the method was invoked.
        2.  Let p be a new promise, and run the following steps in parallel:
          1.  Gather the stats indicated by selector according to the stats selection
              algorithm.
          2.  Resolve p with the resulting RTCStatsReport object, containing the
              gathered stats.
        3.  Return p.

    8.5. The stats selection algorithm
      3.  If selector is an RTCRtpSender, gather stats for and add the following objects
          to result:
        - All RTCOutboundRTPStreamStats objects corresponding to selector.
        - All stats objects referenced directly or indirectly by the RTCOutboundRTPStreamStats
          objects added.
