Implement human color parsing in the command-line by using the standardized CSS 3 subset, well known for styling. Interpret first as text to avoid problems like 'darkgreen' being picked up as 0xDA.

- Also, and make case insensitive by using the strcasecmp() function. Both for colors and modes. The only improvement I can think of is stripping whitespace beforehand.
  - Also, improve digit parsing by using `strtoul()`, previously only FF00FF worked, whereas now we can type things like 0xFF00ff or 0xff00ff.

For example; something like this should work: `OpenRGB.exe -c darkgreen,ff00ff,0xff0000,red,REd,teal,pink,gOLd,AAgoldo,magenta -m breathing`

(`AAgoldo` will throw a `Error: Unknown color: 'AAgoldo', skipping.`; and pick the next color instead, this is intended behavior)
