[SM64] Armatures export with bad rotation

[Anoliah]

When exporting an armature, the mesh part of the object will inexplicably have its x rotation set to 180 degrees without any visual changes to the mesh itself. The exported geolayout will also contain incorrect translate/rotate nodes littered throughout (presumably in an attempt to correct for this?) which causes it to display incorrectly in game. The vertices exported do not differ from previous fast64 versions either, so I'm not too sure what's going on here.

This does not appear to be an issue with objects that do not use armatures. Level exports aren't effected by this either.

Did a git bisect and #625 appears to be the commit that introduced this issue

are we back into the setOrigin/applyRotation hell? 😭
