dichromat 2.0-1

• Added pointers to the colorspace package and base R in a new startup message. The colorspace package provides better functions for simulating color vision deficiency: simulate_cvd(), deutan(), protan(), tritan(). More modern robust color palettes are available in hcl.colors() and palette.colors() in base R as well as further tools in colorspace.
