Turn LCh to CMC.

The CMC colourspace is described in “Uniform Colour Space Based on the CMC(l:c) Colour-difference Formula”, M R Luo and B Rigg, Journal of the Society of Dyers and Colourists, vol 102, 1986. Distances in this colourspace approximate, within 10% or so, differences in the CMC(l:c) colour difference formula.
