1. Added support for loading sub-objects in .OBJ into a generic attribute. 2. Added missing mesh_are_equivlent classes needed for certain unit tests. 3. Updated javascript decoder reflecting our latest changes + added support for GeometryAttribute::custom_id() method. 4. Added checks for valid quantization bits to our draco_encoder app.
