Adds support for exporting animations for foreground models. It's not
perfect and doesn't handle the Jak 2/3 animations very well in some
cases (scale can often get messed up, especially for the LZO compressed
ones, I have no idea what is going on with the data in those art groups
sometimes, so that'll have to be revisited later...), but it does a
decent job on Jak 1.
Additionally, the `build-actor` tool has also been changed to support
setting the `master-art-group-name` and `master-art-group-index` fields
to allow for custom art groups to link their animations to a different
master art group, which lets you add custom animations to vanilla art
groups.
This adds a feature to `build_actor` to support importing skeletons and
animations from .glb files.
Multiple animations are handled and will use the name in the GLB. The
default `viewer` process will end up playing back the first animation.
There are a few limitations:
- You can only have around 100 bones. It is technically possibly to have
slightly more, but certain animations may fail to compress when there
are more than ~100 bones.
- Currently, all animations have 60 keyframes per second. This is a
higher quality than what is normally used. If animation size becomes
problematic, we could make this customizable somehow.
- There is no support for the `align` bone.
