Resprites kitsune masks and makes them adjustable (#86950)

## About The Pull Request
Resprites the kitsune mask, making it so it looks more foxy and fixing
some consistency issues with the mob sprite such as the addition of the
top stripe while making the color scheme consistent with other GAGS
items.
Kitsune masks are also now adjustable by using them in-hand

## Why It's Good For The Game
Makes the mask look cleaner, consistent and better looking while giving
players an option to adjust the mask at will, allowing for more
customization options.
