Animation support

[pablode]

glTF animations are currently not supported. They are described in spec section 3.11.

animation support would definitely be great!

In another repository(GLTFKit2), the maintainer described the difficulty of parsing gltf animation to load in Realitykit. Are these problems somewhat related to the challenge we face for guc to integrate animation translation as well?

It does not seem like the USD spline library (some info here and here) which I'm going to use has this kind of restriction.

Unfortunately, the library is still not mature enough. Although the API and serialization have been implemented, it's still lacking the evaluation and visualization parts.
