this is cool. no objections. thank you for taking this on! curious if you have any api feedback improvement ideas?

find peer via discv4 -> p2p handshake -> eth handshake -> listen to msgs

maybe @mattsse has thoughts on API improvements so holding off on merging

Don't have any immediate feedback, setting up each layer was clear + intuitive enough
