Reporting Packet Receive Timestamps for MOQ

[PFpengfeng]

Currently, BBR is employed as the default congestion control algorithm (CCA) in moq-rs. Other algorithms, such as WebRTC's GCC, may be able to achieve better performance. However, QUIC lacks a mechanism to provide feedback on packet receive timestamps, which is indispensable for GCC. Although [I-D.draft-smith-quic-receive-ts] proposed a solution, it was not adopted. Therefore, could moq implement a mechanism, perhaps through a new control message, to achieve the same objective?

Hey @PFpengfeng

You might be interested in this Quinn fork that implements receiver timestamps and GCC. I haven't tried it yet. Independently for work, I ported the C++ GCC code to Rust: https://docs.rs/goog_cc/0.1.0/goog_cc/
