SRT transport protocol push streaming.

At present, SRT is a common mode of push.

The issue mentions adding SRT push streaming support to a Rust media server. Look for existing transport protocol implementations (like RTMP, WebRTC) in the codebase to understand the architecture. Check for network handling and streaming modules to see where SRT integration would fit. Determine what 'push streaming' entails in this context and what a complete implementation requires.
