Add new colormaps for MITK
Summary:
I want to add four new and shiny colormaps for MITK:
- plasma
- magma
- inferno
- viridis
These cmaps are awesome, because they are suitable for vision impaired people AND work in grayscale
Test Plan: I tested the colormaps with a custom nrrd file. They look good.
