* [FBX] Allow export multi materials per node
Previously it was assumed that each node would export a single material. This removes that
assumption, and also allows for exporting multiple meshes with a single node. Previously they
would each be seprated into their own node.
* Support for animations with multiple meshes too

While one of the throws in the function did indeed close the open stream,
several didn't.

Previously tangents were not being exported. If they are present, they should also be properly
exported.

The heap-use-after-free vulnerability occurs in the
CallbackToLogRedirector function. During the process of logging,
a previously freed memory region is accessed, leading to a
use-after-free condition. This vulnerability stems from incorrect
memory management, specifically, freeing a log stream and then
attempting to access it later on.
This patch sets NULL value for The DefaultStream global pointer.

If mesh is validated after AttributeBegin call, then
the AttributeBegin is never closed with an
AttributeEnd, causing problems in pbrt.

Previously it was possible that the number of vertices between the mesh and morph mesh varied.
This may have caused problems in tools like Blender, and this ensures there's a 1-1
correspondence between vertices.
In addition, exporting doubles broke meshlab on import, so now it exports floats.

Previously GLTF meshes were created even if there were no faces, which lead to GLTFs which were not technically valid.
I believe this fixes the problem I was encountering, but I've not been able to test it because of some Mac compile errors. Will test on a windows machine at some point.

In all other instances where we set mErrorString inside a catch block
we also set mException. I think that this was an oversight.

assigning s_pNullLogger to the parameter "logger" is definitely wrong.
However, custom logger previously set from user must not be deleted.
The user itself must handle allocation / deallocation.
Some blendshapes don't have normal transformations, but Assimp currently requires that normals
be present. This removes that, and won't populate the normal field.
