Implementation of CVD-friendly colormaps to HawkEye/HawkEdit

[wx4stg]

A few days ago, Sunday 8 January 2023, NCAR held a workshop on the use of lrose for research. One of the points of discussion that was brought up was the implementation of a colormap that is friendlier to those with color vision deficiency.

A few weeks ago, there was a conversation on twitter that then turned into a github issue for further discussion which finally lead to a pull request for the implementation of the "ChaseSpectral" colormap into the py-ART library.

I will disclaim that while I was involved in the conversation there, I did not create this colormap (cc\ @jthielen @mgrover1 and @dopplerchase ), and nor do I have color vision deficiency. However there has been some discussion on twitter with CVD and several of my classmates at college are, and they all seem to much prefer the to the standard NWS reflectivity and velocity colormaps.

I have opened NCAR/lrose-displays#1 which include the "balance" (for velocity) and "chaseSpectral" (for reflectivity) colormaps from pyart which provide this. These can be imported into Hawk(Edit/Eye). I have also created the fork https://github.com/wx4stg/lrose-core which includes chaseSpectral as a default, I think, but I was unable to figure out how to compile HawkEdit and it does not show up in HawkEye, so... if the project maintainers want this as a default colormap, I'm going to need some help with that :)
