    5.3.  RTCRtpReceiver Interface
      interface RTCRtpReceiver {
         Promise<RTCStatsReport> getStats();
          ...
      };

      getStats
        1.  Let selector be the RTCRtpReceiver 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
      4.  If selector is an RTCRtpReceiver, gather stats for and add the following objects
          to result:
        - All RTCInboundRTPStreamStats objects corresponding to selector.
        - All stats objects referenced directly or indirectly by the RTCInboundRTPStreamStats
          added.
