Find workaround for getting lipsync to animate child meshes too (teeth/tongue...)

[James-Leonis]

Describe the bug
Whenever applying lipsync, the mouth moves perfectly, but the teeth/tongue do not. I'm not sure if this would qualify as a bug or if it would be a feature request.

This is more of a lipsync thing than a mpfb thing. What you do with the lipsync addon is animate the shapekeys one one specific mesh. The lipsync addon does not seem to have a concept of shapekey animation of shapekeys on multiple linked meshes.

This said, maybe it'd be possible to find a workaround from the MPFB side. Basically, the lipsync procedure needs to be repeated for each child mesh, but as it stands it is difficult to get the relevant shape keys interpolated onto for example the teeth.
