Add back "miscellaneous" matplotlib colormaps

[mickaellalande]

It would be nice to have by default all the colormaps from Matplotlib (https://matplotlib.org/examples/color/colormaps_reference.html) in particular the jet one for example that I was used to pick, because more visible than the Spectral one in Proplot. But the terrain one is also useful, etc. I don't know if there is particular attention for colorblind people and if it goes in that way or not (I don't have any knowledge on that)?

So the reason we removed jet is to strong-arm users into using "perceptually uniform" colormaps -- check out this workshop @bradyrx and I hosted (see the slides in the "powerpoint" folder and the notebooks in the "notebooks" folder).

But I think you're right, it is probably preferable to keep these colormaps "resistered" but just hide them from the colormap table (I do the same thing by hiding matplotlib's CSS colors to push users toward xkcd colors). Also topographic colormaps kind of defy the typical colormap categorization into sequantial/diverging/qualitative, so even though they are generally not "perceptually uniform" there's no reason they should be deleted.

I will add back the colormaps then maybe add an ignore keyword arg to show_cmaps that can be used to ignore certain categories. By default, it will ignore the maps in the "Miscellaneous colormaps" category.

Ok, great thanks for the explanations, I was a bit expecting this kind of answer, but it was still unclear for me. Because many "old" supervisors will ask for this jet colormap to "see something", however next time I will show them your presentation 🤣.

This was fixed by ce4ef6a. "Bad" colormaps are no longer deleted
