chore: extract dayz from valve

[CosminPerRam]

DayZ runs on Valve A2S but it is modified quite a bit and their data types needs to be read differently than standard ones, this PR extracts everything dayz related into another protocol file (which still runs on top of the valve protocol file), clears up a lot the cluttered Valve protocol file.

[CosminPerRam]

Responses are as expected, and now it is also possible to extract only the 'pure' valve response out of it as the game query implementation is completely compatible to 'vanilla' A2S.

another possible thing to do would be to still detect DayZ in the Valve protocol (via its app id) and instead of returning the valve response, run the dayz protocol, but I dont really know a reason to do this, better yet as said in my previous comment, its now possible to get the valve-only response with no dayz data addons, if you want the addons, run the DayZ protocol (this is default behaviour).

This is incredible @CosminPerRam! Thank you! 🙌 🚀

I was wondering, will this be part of the version 4.3.2? I'm particularly interested in this commit (90e26bb), which I think is also related to this issue (#440).

That specific commit no, that's changed behaviour regarding how players (or bots) are added into the list and that's a breaking change, so its for 5.X
