Ensure that categorical colormaps are registered as ListedColormap #39

Generally categorical colormaps should be registered as ListedColormap instead of a LinearSegmentedColormap so the Glasbey colormaps should be switched.

__init__.mpl_cm is always using LinearSegmentedColormap but it needs to have some added logic to use ListedColormap for categorical colormaps. Perhaps through some mapping on the groups/name parameter.
