## About The Pull Request


Adds missing sprites for digitigrade legs and teshari, going down this
(new) list

The digi sprites are the main focus, I am adding teshari sprites too
while I'm at it
(I want to one day add a lot more teshari sprites, but there's a LOT
more missing)

Also deletes "suit/henchmen" because it doesn't actually exist (is one
line of code, no sprites)

Sprites added for:
- black turtleneck
- floortile camo
- britches' dress
- armored dress (blueshield/netra)
- lilac dress (rank/lace)
- sleek modern coat (cybersleek)
- long modern coat (cybersleek/long)
- fancy suit
- texan formal outfit
- dimmadome formal outfit
- Dragon undergarments (blutigen_undergarment)
- occult collector's outfit (under/occult)

## Why It's Good For The Game

Less missing sprites good!
## Proof Of Testing

(Note that the sprites on the middle character look slightly off in the
images due to them being differently sized, the sprites in the files
look the same as the left minus the digi leg edit.)
