.motstm_data support and .motstm_data .anm files fix?

[Andree12]

So, I managed to extract the .anm files inside .motstm_data file but when I tried to import them with your importer, it glitches up the animation but at least it works.

So, can you add in support for loading .anm files in .motstm_data similar how you done with .mot files and fix up the .anm files from .motstm_data files please?
