Title: Implementation of DIN99o color space

Implementation of the DIN99o color space, an optimization of the DIN99 color space, similar to DIN99d.
As glenn-sweeny already mentioned there exist a couple of modifications/optimizations of the DIN99 color space. I found that DIN99o has become increasingly important in color science, as the growing use of this color space in academic literature and, for example in the printing industry (Fogra Graphic Technology Research Association), show.

As glenn-sweeny already mentioned, if this implementation is not considered relevant enough for the project, I will happily keep it as a private extension.

Some references to DIN99o are:
