add a bunch of hair pieces

[Retrino]

About the PR

adds a new type of hair piece, hair splits. also adds bangs from existing hairs. sprites made by their original owners (mostly thrush and walp i think?), i just sliced and diced them

hairs that got split: messy waves, flick, violet, long waves, smooth waves, rock ponytail, glam ponytail, wavy ponytail, split twin tails

hairs that got bangs: combed front, combed front short, long front, spoon

Why's this needed?

we don't really have too many options for horizontal color differences in hair styles like we do with the faded options, could make for some interesting styles. more bangs is also cool, since we have a bunch of hairs with a flat hairline

Changelog

Should probably have random_allowed = FALSE set on these or you'll get some veeeery wacky random characters
