FIX(positional-audio): Update Among Us plugin to work with v2020.12.09s
The reason why the signature has to be stricter now is due to a very similar function being present at an earlier address:
il2cpp:10E99B02 83 C4 08 add esp, 8
il2cpp:10E99B05 84 C0 test al, al
il2cpp:10E99B07 74 39 jz short loc_10E99B42
il2cpp:10E99B09 A1 AC 7C C5 11 mov eax, HLBNNHFCNAJ__TypeInfo ; HLBNNHFCNAJ
il2cpp:10E99B0E 8B 40 5C mov eax, [eax+5Ch]
il2cpp:10E99B11 8B 38 mov edi, [eax]
il2cpp:112CC4B8 83 C4 08 add esp, 8
il2cpp:112CC4BB 84 C0 test al, al
il2cpp:112CC4BD 74 39 jz short loc_112CC4F8
il2cpp:112CC4BF A1 54 7F C5 11 mov eax, FMLLKEACGIO__TypeInfo ; FMLLKEACGIO
il2cpp:112CC4C4 8B 40 5C mov eax, [eax+5Ch]
il2cpp:112CC4C7 8B 00 mov eax, [eax]
FMLLKEACGIO is AmongUsClient, the object we need.
See https://wiki.weewoo.net/wiki/Translations for more info on the obfuscated names.
