Describe the bug

There is a bug at https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c/blob/master/src/source/PeerConnection/Retransmitter.c#L108

sequenceNumberList should be replaced by validIndexList

For RTC sequence number <= 65536, sequenceNumberList and validIndexList have the same value, the code still works.
At 2Mbps, after 300 seconds of livestreaming, KVS SDK will fail to put retransmited packets back into rolling buffer and the video quality could suffer.

Expected Behavior

Re-transmitter always works

Current Behavior

Re-transmitter fails after sending 65536 RTP packets

Reproduction Steps

after sending 65536 RTP packets, re-transmit will fail with STATUS_ROLLING_BUFFER_NOT_IN_RANGE

This ticket is exactly the same as #1453
The previous ticket was submitted two years ago. I am surprised that it was never fixed
