 Note that cgltf does not load the contents of extra files such as buffers or images into memory by default. You'll need to read these files yourself using URIs from `data.buffers[]` or `data.images[]` respectively.
-For buffer data, you can alternatively call `cgltf_load_buffers`, which will use `FILE*` APIs to open and read buffer files.
