Started following along with this video: https://www.youtube.com/watch?v=Iapc-qGTEBQ&ab_channel=CodingTech

Decided to implement the async conn listener/broadcast listener differently than the video.

start server:

cargo run

From additinoal terminal windows, connect to server with:

telnet localhost 8080

Type out a line and press enter, and the messages will show in the other terminal windows.

There's a bug, something panics, I think it's related to client disconnects, not sure.
