Summary: Providers observers with insight into ACKs received. Works for both client and server transport. Attempts to prevent wasted memory by removing any allocated memory for ACK events if no packets in flight. In tandem, reduces allocs by _not_ removing allocated memory when packets are in flight (as this means more ACK events will occur soon...).
