LibVideo: Implement CICP color space conversion
This adds a struct called CodingIndependentCodePoints and related enums that are used by video codecs to define its color space that frames must be converted from when displaying a video. Pre-multiplied matrices and lookup tables are stored to avoid most of the floating point division and exponentiation in the conversion.
