Hat Kid e6260e48ab decompiler: support animation export and support master art groups in build-actor tool (#4260)
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.

water111 b3cdcf3a67 custom actor, fix animation compression (#3802)
Fix a missing scale factor when using the large mode in the animation
compressor. This would make some joints have a translation of near 0 if
the original animation had stuff moving a large distance

water111 a2f9d36332 Fix animation processing interpolation bug, crash on no merc material (#3794)
Fixes the issue with animations doing a full 180 degree rotation and
disappearing. The quaternions in the GLB export "flip", and when
interpolating animation frames in between a flip, we got bogus
quaternions.

Fixes https://github.com/open-goal/jak-project/issues/3786

Also fix a crash in `goalc` when using merc models without any
materials.

water111 fe29eae395 Background improvements for custom levels (#3672)
This only applies to the background for now:

- support for alpha for vertex colors in custom levels
- switch time of day palette generation from octree to k-d tree
- support for alpha masking in custom levels
- support for transparent textures
- support for envmap in custom levels

water111 f2e7606f1b [build_actor] Add skeleton and animation support (#3638)
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.
