Incorporating cividis colorscheme

[parekhpravesh]

Hello,

Nuñez et al (2018) https://doi.org/10.1371/journal.pone.0199239) introduced an optimized colormap that is more inclusive of people with color vision deficiency. Maybe this optimized version of viridis, named cividis could be incorporated into MRIcroGL and SurfIce?

I have added a clut file for cividis; I looked up the colors used in viridis and replaced them with the corresponding RGB from cividis. A naive version of clut with all 256 nodes (which is not practical) is also attached. I have changed the extension from .clut to .txt
cividis.txt
cividis255.txt

A quick side-by-side comparison of viridis (left) and cividis (right) is below:
