Big revamp of colour palettes: updated colours and names of existing
palettes (now more colourblind-friendly), dropped old palettes (“glue”)
and added new palettes (“bodied”). Palettes are now defined as
qualitative, sequential or diverging.
Added functionality to interpolate between colours for sequential
and diverging palettes.
technocolour 0.1.0
Added six colour palettes.
Added functions to list available palettes, make palettes, visualise
palettes, and print palette info.
