Describe the Enhancement

When testing the pull request for MET #1528, Michelle noted that it would be nice to provide a colortable in MET that's well-suited for plotting topography. The data/config/colortable/NCL_colortables directory contains MET-friendly versions of the NCL colortables derived from:
https://www.ncl.ucar.edu/Document/Graphics/color_table_gallery.shtml

MET currently has 56 NCL colortables but it looks like there are several new ones, including a few with "topo" in the name. This task is to update the NCL colortables directory to include the full set of 270. Use files ending with ".rgb" from here:
https://github.com/NCAR/ncl/tree/6.6.2/ni/src/db/colormaps

Include the conversion script directly in the repository.
