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.
