srt-runtime 0.4.0

SRT (Secure Reliable Transport, draft-sharabayko-srt-01) packet codecs + sans-IO HSv5 Caller-Listener and Rendezvous handshake state machines, an ARQ reliability engine, a TSBPD delivery scheduler, LiveCC packet pacing, FileCC window-based congestion control, optional (crypto feature) payload encryption, and an optional (tokio feature) async UDP socket adapter; no_std core.

# `tokio` enables the real-socket async UDP adapter over the sans-IO SRT

# hosted targets — the `no_std` packet-codec core stays clean without it.
