Pyfda crash with matplotlib 3.2

[Magine96]

With matplotlib 3.2, pyfda crashes with the attached traceback. The root cause is that the names for reversed colormaps like hot_r have been eliminated from cm.datad. New colormaps like viridis are also missing (matplotlib/matplotlib#5202).

The crash is being fixed by commits 38f7698 and 2bc1949, new colormaps are still missing.
