Add color remapping to remap colors

I'd rather have an initial drop-down that works similarly to the palette dropdown.
Recolorable Palette:

• Optimized (I'll change out the whole clover thing for something that works better later)
• OpenRCT2
• Custom

With custom exposing the drop downs for the individual colors.

That way we don't overwhelm new users with options that they don't need to care about yet.

Also please test this with the full work flow all the way up to in-game to verify that the colors are remapped properly

What colors would be chosen for "optimized"? Personally J am pleased with the results of violet, magenta, and teal as the three remap colors
