colorcet.m (essentially the "canonical" upstream, though created by cmap.m) offers more aliases for colorcet maps than are possible via CET_to_py.py, since the aliases dict is a one-to-one mapping of descriptor name to alias (e.g. linear_kryw_0-100_c71_n256: 'fire')

Describe the solution you'd like

Change aliases in CET_to_py.py to a dict of lists where each descriptorname can have multiple aliases. Rework uses of aliases to handle a list of values returned for each key.
