Reorganized code and added some feature and listed restrictions. Some gltf models do not work yet.

Actually, it was broken and it that code has no maintainer.

It seems vox loader is not working properly...

* Add DrawCylinderEx and DrawCylinderWiresEx

* Modify examples/models/models_geometric_shapes.c to show the
usage of DrawCylinder(Wires)Ex

* Simplified DrawCylinder and DrawCylinderWires to use the -Ex versions.

* This reverts commits f49b2598dd and
4542b32e4e.

* Fixed formatting.
Renamed base_angle to baseAngle.
Remove most of the raymath.h calls.

* Added check for empty cylinder.

* Added check for empty cylinder.

* Fix bug.

* Supress most warnings on rmodels.c

NOTE: unused symbols have been deleted and the following report will show in what location they were previously.

Unused symbols:
- ArrayInt - vox_loader.h: line 84
- initArrayInt - vox_loader.h: line 168
- insertArrayInt - vox_loader.h: line 175
- freeArrayInt - vox_loader.h: line 186
- offsetX, offsetY, offsetZ - vox_loader.h: line 610
- chunkTotalChildSize - vox_loader.h: line 623

Other warnings:
- initialization discards 'const' qualifier - vox_loader.h: line 572
- incompatible types for VoxVector3 and Vector3 - rmodels.c: line 5748
- incompatible types for VoxColor and Color - rmodels: line 5749

* Remove ToVector3 and ToColor functions and assign values directly

* Fixed gltf missing transforms on load

mend

* extracted Matrix calculation in to static method and added skinning check

* fixed formatting

* Fixed write to access to nullptr when animation has no normals

* Refactored UpdateModelAnimation to only update changed vertices when needed (allows for multi animation playing)

* add check for models that were missed during BindGLTFPrimitiveToBones to not segfault the program

* fixed id mismatch between animation and model

* draft on fixing the mesh to skin mapping

* dont look at this

* removing debug info

* Add function DrawCubeTextureRec

* Add EOF newline

* Remove unneeded example

LoadModelAnimations takes an `int` for the animation count parameter.
The animation count should never be negative, so it makes sense to
specify it as unsigned in the API. This matches the API for
UnloadModelAnimations, which expects an unsigned int. Both GLTF and IQMM
also store the animation count internally as unsigned, and we were
casting to a signed int for no reason.

GLTF actually uses `size_t` internally, so we're technically risking
overflow, but having 2^32 animations seems unlikely.

raylib modules have been slightly renamed to add some identity and note that they are independent modules that can be used as standalone separate parts of raylib if required.

The renamed modules are:
 - `core` -> `rcore`
 - `shapes` -> `rshapes`
 - `textures` -> `rtextures`
 - `text` -> `rtext`
 - `models` -> `rmodels`
 - `camera` -> `rcamera`
 - `gestures` -> `rgestures`
 - `core` -> `rcore`

All the build systems has been adapted to this change.
