Adjust importer to read directly from the source .itermcolors
files in the upstream repo. Extract some author information
from the comments in those files.
All data is now fetched (and cached!) via relatively minimal
http requests rather than requiring a git repo locally.
Also search for .yml files in base16 repos; found another
couple of schemes this way.
The toml files under assets/colors are no longer read by
anything in the repo. I plan to remove them, but since the
docs reference them as examples, I will first ensure that
there are docs and tooling that explains how to write and
share your own scheme files.
wezterm.color.parse() returns a color object that can be assigned in the
wezterm color config, and that can be used to adjust hue, saturation and
lightness, as well as calculate harmonizing colors (complements, triads,
squares) from the RGB/HSL color wheel.
