Fixed incorrect mapping of meshes to blend shape bind mesh indices.

[ExpiredPopsicle]

This was additionally causing issues adding surfaces inside adjust_mesh_zforward.

When attempting to add a surface, the mapping mismatch would cause the number of blend shapes to differ between the arrays being added and the mesh, which would cause the mesh.add_surface call to fail.

That failure to add a surface would then cause more issues in _create_animation_player.

Can you provide an issue with a mrp?

Unfortunately, I do not have permission to share the model that was reproducing this.

@copygirl sent me the model, after getting permission from the original owner to share it.

I can try to generate a contrived case, but I'm not sure if the Blender VRM exporter I use is capable of creating a case of it from scratch.

Maybe we can contrive a smaller test case.

From what I know, the model was just a basic VRoid Studio model, but may have been edited in Unity to re-parent the hair-based tail to the body, rather than the head?

People have been using SnekStudio with it for a bit now.

I wanted to make a testbank, but we never got the people to help out with it. So SnekStudio is doing more testing with shipping the addon than we are.
