Add ColorSpace class

The ColorSpace class can be used to create an RGB color space from
either primaries/whitepoint or an RGB->XYZ matrix.

The primaries and whitepoint are in xyY space. A utility function
is provided to compute xyY coordinates from XYZ coordinats.

The class contains numerous functions to create common RGB color
spaces (sRGB, DCI-P3, etc.).
