UseHiDefCharacters: use GH00 anims from Media folder to fix hair

Anims in Media folder include hair anims, while the normal Chr folder anims don't.
Some reason the Media folder ones go unused, not sure if these are some newer versions that added them in (but accidentally went unused), or maybe they're older ones before they removed them for some reason.
