TODO add more as I find them

[Promises]

Could you also list unknown packets, and the ids for the known ones? could help figuring out the rest?

[Jameskmonger]

@Promises good suggestion. I've listed all outgoing opcodes for any packets which aren't done. Some of them are in the list, others I don't know what they do yet.

[Jameskmonger]

The main piece of this work is done 🎉

I'll leave this ticket open for now as there are some nice-to-haves left (cs2, anticheat etc).
