BIP324 Proxy: easy integration of v2 transport protocol for light clients (PoC)

Good point about the port, I changed it to 8324

Good to hear your first test worked, looking forward to more feedback.

My next step is to refactor the code and use the btcd packages to send and receive v1 messages. I also want to see if I can hack btcd to make v2 connections using the code I already have.
