Use NCL colortable in python matplotlib colormap without install new packages
All colortable in NCL exist in cmap_data.tar.gz (Ref: https://www.ncl.ucar.edu/Document/Graphics/color_table_gallery.shtml)
Unzip the compressed file and place on the same directory with the python code
No compatibility issue
You can use reversed colormap for any colortable just by typing "_r" after the colortable name (i.e., rainbow_r)
