Interface SerialSessionReceiveReplayOptions

Retains the last N decoded text chunks (one emission per onChunk from the read pump) in the replay buffer. Not the character count. Higher bufferSize uses more memory.

When true, the session uses a replay buffer for SerialSession.receiveReplay$ for each open connection. When false (default), receiveReplay$ is the same hot stream as SerialSession.receive$ (no chunk replay).
