The Height Map plugin colormaps are poor. #437

I wouldn't complain about this normally, but I greatly appreciate DuetWebControl and this is how I can give back. :)

The colormaps for height, 'Terrain' and 'Heat', in the plugin are poor because: 1) They don't have very much contrast and have uneven contrast (low perceptual length, non-uniform perceptual derivative) 2) Both are terrible for people with red-green colorblindness, the most common form of colorblindness. 3) A diverging colormap would be better for a variable that deviates around a mean.

More info: Matplotlib guide to colormaps: https://matplotlib.org/stable/tutorials/colors/colormaps.html A talk by MPL: https://www.youtube.com/watch?v=xAoljeRJ3lU A paper: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8309845/

An easy solution would be to ask MPL if we can copy some of their colormaps. Alternatively, I can design some new ones specifically for the plugin.

Cheers, -Mike
