Improvement of colormaps images and more by zmoon
- Use ListedColormap instead. Simpler and gives the same result for the non-categorical ones since they have N=256.
- Clean up the .cm namespace so that it is easier to use
- Fancier show_cmaps plotter, and show the result in the readme under its code demo.
- show_cmaps added to the top-level namespace
- __all__ added to the top-level __init__.py
- In readme, import cmcrameri.cm as cmc for consistency with the 'cmc.<name>' form for the registered cmaps added in
- scrallen: added plt.cm.register_cmap commands...
- Add example of using a registered cmap name to the readme
- Running cm.py directly generates the colormaps.png
- Update the links to Crameri's website
