glTFLoader issues with models that contain over 60k vertices

I'm trying to use the glTFLoader to load in a glTF files (converted from obj) that can be around ~100k vertices, or more, where the indices need to be stored as integers instead of shorts. It seems however that the way in which the loader is build only supports a limited amount of vertices (CesiumGS/obj2gltf#12 (comment)).

line 237 in glTFLoaderUtils.js

The componentType in this case is an UNSIGNED_INT, which isn't being handled at the moment.

Any guidance or help would be much appreciated if possible! Thank you!

Have you tried with the new GLTFLoader?

@mrdoob thank you for pointing me to that. After adding int to component types, 5125: Uint32Array (https://github.com/mrdoob/three.js/blob/master/examples/js/loaders/GLTFLoader.js#L100), my model loaded successfully!
