Fixes a crash due to null normals on converting FBX model. Refactors processVectors to read MappingInformationType and ReferenceInformationType into variables and handle IndexToDirect references generically using <layer>.<name>Index. This moves index-based remapping before vertex-based reindexing and replaces the hardcoded NormalsIndex key, fixing exports (e.g. Blender 4.1) that use IndexToDirect reference types. Note: This was authored by Codex 5.4 and tested by me, allowing my FBX models exported from Blender 4.1 to load correctly without crashing.
