matplotlib.cm.get_cmap is removed from version 3.9

[zhaleh-safikhani]

matplotlib.cm.get_cmap is used in marsilea to get color map and you call it in plot_associations.
so now I get this error: module 'matplotlib.cm' has no attribute 'get_cmap'

Hi @zhaleh-safikhani ,

Thanks for the heads up! I've checked and this new version seems to still be unstable (I cannot seem to make matplotlib.cm.ColormapRegistry.get_cmap work) so I'll wait until they solve their issues. For the time being, keep matplotlib version to anything below 3.9.0.

Actually you are right, the code only fails when using marsilea, I've already opened an issue in their repository: Marsilea-viz/marsilea#35
