Add new sprites and coloring methods for basic jumpsuits.

What Does This PR Do

Adds new sprites for basic jumpsuits, and a new coloring method (swap_palette) that should make sprites easier to maintain and update, giving custom palettes for each color of jumpsuit while still maintaining just one sprite across all simple color substitutions.

This is a work in progress. I will add images and testing information when it's ready to review.

Why It's Good For The Game

It's easier to update one sprite than many, easier to update a palette in a registry than to repaint sprites across six unique species, and I think Kida would appreciate the new sprites fitting over their massive shoulders.

Images of changes

Will add later.

Testing

Still testing and getting everything working.

First round of color tests. THESE ARE NOT NECESSARILY THE FINAL COLORS. That's up to your feedback and also what I think when I return to them later with fresh eyes.

Suits featured: red, orange, yellow, green, blue, purple, black, grey, white, brown, dark blue, dark red.
Skirts featured: pink, yellow, light blue, aqua, light purple, yellow green, light red, light green, light brown.

So give me all your feedback! Are the shapes working for you? Do any colors seem too bright, too dark, too intense, too muddy? Let me know because I will be coming back around.

Second round of color tests! THESE ARE ALSO NOT NECESSARILY THE FINAL COLORS. That's up to your feedback and also what I think when I return to them later with fresh eyes.

This time around, I tried to more closely replicate the lightness, saturation, and ramp shapes present in existing jumpsuit sprites. This made the colors overall more muted, but I think the relationships between the shades look more natural. What do you think?

Color test 3. Again, not necessarily the final colors, but I was more focused on the sprite changes this time. The upper left skirt is light red this time, not pink, for clarity. The only colors with slightly modified palettes are light red and regular red.

The main sprite changes were underarm shadows, rolldown reshading, and my attempt to make sure all the uniforms look like they have a collar, instead of some having a collar and others having a vague shadow. Oh, and the new inhands and item sprites. I'm not sure I'm going to keep the east/west inhand positioning, but as always, I want to hear your feedback.
