* clean up SetModelBoneRotationInternal
* clean up a few float <-> double and unsigned <-> signed warnings
* fix more warnings
* further clean up warnings

* initial work on bone getters, matrix hell
(the matrix/vec3 multiplications are probably wrong af, just gotta add more stuff 'till i can test it)
* clean up matrix math
* GetBone/TransformByBone
* fix GetBoneFramePose
* fix ObjectToWorldMatrix
* fix missing array resize
* raw matrix getters (for use with gutamatics/etc)
* reverse matrix mult order
* replace GetBoneLength/GetBoneDir with GetBoneBaseTRS
* fix GetBonePosition, remove GetBoneWorldMatrix as it's useless
* GetBonePosition
* deduplicate code
* rename GetBonePosition to GetBoneBasePosition to avoid confusion
* GetBoneBaseRotation
* GetBonePosition helper function
* forgot include_offsets
