HMM2.0 (#149)

Browse Source 
These changes were all made by @dev-dwarf. Many thanks for his work on this!

* Renaming

* First Pass on 2.0UpdateTool

* Another pass on UpdateTool, changed name

* Another pass on UpdateTool, changed name

* Do Renaming

* Working on Angles Consistency

* Passing Coverage

* Remove unused arc-tangent functions

* Change macro defaults

By default if user is overriding trig functions assume their input and internal units are the same.

* wrap in AngleDeg instead of AngleRad

* Remove HMM_PREFIX configuration

* Fix for Slerp

Justified by most implementations of Slerp. EX: http://number-none.com/product/Understanding%20Slerp,%20Then%20Not%20Using%20It/

* Handedness Changes

* More renaming. C11 _Generics

Generics enable by default when available (see lines 97-104). User can also force them by defining HANDMADE_MATH_C11_GENERICS

Also fixed some missed things w.r.t renaming. My old tool didn't catch cases like HMM_MultiplyVec3f needing to be HMM_MulV3F instead of HMM_MulV3f.

* Reuse more SSE codepaths for Quaternions

Also improved quaternion tests. More work could be done here, see discussion here about optimizing slerp: https://discord.com/channels/239737791225790464/489148972305350656/1055167647274246265

* Just saving these alternate versions of SLerp

* Reduce V4/M4 Linear Comb. codepaths

* Simple implementation of 2x2 and 3x3 basic matrix operations.

Also renamed Transpose to TransposeM4, so that we can have TransposeM2,M3

* Norm is dead! Long live Norm!

As can be seen from the tests, precision has declined quite a bit from using the FastNorm implementations for various things. We can only guarantee about 0.001f precision for anything where a norm happens now. If this is undesired we can change back easily.

* Started work on Matrix Inverses

TODO: Tests for simple 4x4 Inverses

* Matrix Inverses + Tests

* Generics for Matrices and Rename MXd/f functions

* Fixes + Better Output for UpdateTool

* I think I count as a contributor : )

* Ported UpdateTool, Inlined my library code.

* Moved tool to different repo

https://github.com/dev-dwarf/HMM2.0UpdateTool

* Remove small test change

* Found some more references to atan functions

* Standardize angle function names, use short names

* Remove other slerp comments

* woops that wasnt meant to be commited.

* Finish changing ToRadians to ToRad

* Fix [] overloads

per https://discord.com/channels/239737791225790464/600063880533770251/1051600188302692402

* Tests for 2x2, 3x3 Matrices and Other Matrix Ops

* Add an option to use Z: [0, 1] range for projection matrices.

This will make HMM more convenient to use with other graphics APIs such as Direct3d and Metal.

* Update test imports

* #if should've been #ifdef!

* Implement requested changes
