z_skin_matrix.c decompiled (1 non matching, 1 non equivalent) (#243)

* func_800A7BE4 and func_800A7C20 done

- func_800A7BE4 copy of "Math_Vec3f_ToVec3s" in z_lib.c
- func_800A7C20 copy of "Math_Vec3s_ToVec3f" in z_lib.c

* done func_800A7A24

* func_800A76A4 done

* func_800A6E10 done

* func_800A6EF4 done

* func_800A6FA0 done

* func_800A72FC done

* Deleted z_skin_matrix.data.s and updated spec

* func_800A730C done

* func_800A735C done

* func_800A7E70 done, func_800A7C60 matching but I'm not happy with it (weird types in function params)

* Corrections. func_800A7C60 in skin_matrix done, Matrix_MtxFToMtx in sys_matrix done.

* func_800A7EC0 nonmatching

* func_800A8030 nonmatching but VERY close (two registers swapped)

* func_800A8030 done

* updating comments

* func_800A7704 done

* func_800A7894 done

* halfway through deciphering mips_to_c for func_800A73E0

* func_800A73E0 functional but non-matching (saved register differences and probably regalloc)

* Renaming some arguments and rewriting comments

* Renamed files across whole project and deleted asm nonmatchings

* ran format.sh

* fixed function name

* fixing multiplcation order in SkinMatrix_MtxFMtxFMult

* Corrections in SkinMatrix_MtxFMtxFMult

* Formatting changes after review

* Changes as per code review

* fixing rename error

* fixing rename error

* rename fixes

* fixing function rename error

* ran ./format.sh

* last couple of changes as per code review

* renamed SetScaling -> SetScale

* Skin_Matrix_Invert -> SkinMatrix_Invert

* Renaming and fixing debug message print
