RIP the BIFF

Added what should be enough documentation for people to spin up their own zap-stream-core:

GitHub

zap-stream-core/README.md at main · v0l/zap-stream-core

Contribute to v0l/zap-stream-core development by creating an account on GitHub.

If something is missing let me know. Also planning on pushing apps to Umbrel and Start9 maybe if people are interested in that?

Added a small realtime metrics section for streamers on zap.stream!
