Fish Ass: ports over large shark tails from CHOMP (#3448)

## About The Pull Request

see title
if you want to see who made the sprites, follow the accreditation chain:
https://github.com/CHOMPStation2/CHOMPStation2/pull/9926

it doesn't fully use all the sprites, because our system here is so much
clunkier to use - if someone wants they can probably bash out several
more tail variants by copying and rearranging the existing sprites

## Why It's Good For The Game

people wanted them, gushed over them in #suggestions, and then no one
did anything, so...
also, 🦈

## Proof Of Testing

yeah i compiled it, they finally showed up in game, thanks #coder-longue

## Changelog

🆑
add: 4 new tail options
image: new tail sprites
