add mirv_viewmodel to AfxHookSource2

Closes #941

Give it a check though. Maybe at very least you want to rename things/put in slightly different way

Hi. Thanks for your contribution. I will have to look into the hook signatures you use in order to add some comments in the code or in doc/ folder of what these functions are and how to find them, because the signatures will probably break with the next larger CS2 update :S
Also if they are part of a vtable, it might be easier and more stable to use that to find them, but maybe they are not (didn't check yet).
I will try to do these tasks before Sunday (unless there's urgent CS2 update breakage of course).

well, these two are pretty straight forward I think, but I don't know if they are part of vtable or not.

Only thing is for some reason your FindPatternString can't find full pattern for second function (ghidra can find it though). So I shorten it a touch, but it's still unique.

Full signature for left/right hand function I got generated with sigga is 40 56 48 83 EC 20 80 B9 69 21 00 00 00 48 8B F1 ? ? 32 C0 48 83 C4 20 5E ? 48 8B 89.

(You need to put two question marks for a byte in FindPatternString , since it's for hex string, 2 hex digits are a byte.)

ye actually, I overlooked that. Works with full one
