TangentsJobExtended extracts data from cgltf accessor and runs geometry::TangentSpaceMesh on the attributes and computes the tangent space.
The /extended folder is meant for running this process. Note that this API might remesh the input and will require corresponding changes that might break previous assumptions.
The general flow of the code is modeled after src/TangentsJob.h
This is not hooked into current code and should have no practical effect on gltfio.
