Change colourspace handling round a bit:1.0-colour-cleanup

- move the essence of GammaLUT into TransferFunction and handle
  different bit depths more neatly
- add ColourConversion to describe input gamma correction, colour
  transformation and then output gamma correction in one class.
- add default ColourConversions for sRGB->XYZ, Rec709->XYZ and
  XYZ->RGB.
