Haroon Qureshi acad9a06e9 Add support for importing GLTF2 animations. 
Refactors the glTF2 internal classes to more closely reflect the structure
of the actual GLTF2 file format. Adds implementations for reading skins
and animations from GLTF2 files into those structures.

Also provides implementations for converting skins and animations from GLTF
into assimp data structures.  Special handling is required for bone weights
since assimp stores vertex-weights-per-bone whereas GLTF2 stores
bone-weights-per-vertex.  Only supports keyframed LINEAR animation data;
STEP and CUBICSPLINE is not currently supported.

Axel Wefers 0e99f1f587 Build fix for 1684 
Requires cast from size_t to uint64 like in other places, otherwise the call to the constructor for GenericValue() is ambiguous.

Fixes #1684

Merge multiple meshes in a node into one mesh with many primtives; write out only one mesh per node 
To do:
- clean up MergeMeshes
- see if there’s a way to do this earlier in the flow

Fix mesh primitive’s attributes’ names 
Per spec

TEXCOORD -> TEXCOORD_0
COLOR -> COLOR_0
JOINTS -> JOINTS_0
WEIGHTS -> WEIGHTS_0

Remove JOINTMATRIX since it’s not supported (and doesn’t seem to be output, anyway)

TANGENT should be added at a later date

Remove KHR_binary_glTF code 
Binary glTF is now part of the glTF2 spec. However, it’s implemented incorrectly, so will be temporarily removed

Sampler improvements; Add new LazyDict method 
Samplers are now imported into assimp internal format from textures;
Samplers have defaults as per spec;
Sampler enums are strongly typed with UNSET values;
Samplers are exported properly;
Sampler filters are exported as well;
Samplers are re-used across textures on export
Default sampler values are not written
