RTMP handshake fix, ReadFull now only reads upto C0C1 instead of waiting on full sequence

 **Not intended for actual use**. The stream key use is not secure and is used to handle directories without a user db system, than to provide auth. Same goes for the SRT passphrase. Also just accepts connections so will get DDOS'd immediately.
 
+**Update**: main branch has been tested over a network. RTMP should now work fine, SRT "works" with a few modifications. The RTT ping log-buffer slice must be extended depending on network latency (try ~2x latency/10ms, could adjust automatically, but eh). Also will inevitably crash on poor connections due to the lack of DROPSEQ handling, but will work perfectly fine during the initial 3-10s you get.
+
 Limits to a single stream at a time, mostly for the lack of db to handle connections and user information rather than concurrency problems.
 
 Currently always transcodes to vp9 + opus, segments to fragmented mp4. Creates one segment playlist, no manifest. Uses ffmpeg
