Tracking: add all of the protocol messages

[tdelabro]

Under src/network/wire/lib.zig are the methods to send messages to another node, by writing those on a "wire".

Under src/network/protocol/messages/version.zig is the first message we have, along with the methods allowing to serialize it into the wire.

Here is the list of all of the protocol messages: https://developer.bitcoin.org/reference/p2p_networking.html
