Detailed Description

Defines a color-space for DVB-sub images. This maps to a single CLUT in the spec. This holds a map of the byte codes to the respective RGB colors. This also handles getting the default colors when none are provided and converting between bit-depths if applicable.

When handling bit-depths, this will attempt to use the bit-depth provided before converting upward then downward. Each color is only set for that specific bit-depth; meaning different bit-depths can have different colors mapped to the same byte-code.
