Number of received FEC bytes is used for the WebRTC.Video.FecBitrateReceivedInKbps UMA histogram. Before this cl, that value is based on a FEC packet counter updated by ReceiveStatistics::FecPacketReceived. This cl deletes that method, and instead adds a byte count to the FecPacketCounter struct, which is maintained by the UlpFecReceiver and used for other FEC-related stats.
