Document `light_*` colors?

[joshorr]

I was trying to figure out how to get the bright colors that Pycharm terminal supports. Took my some time before I released there were undocumented colors, the light_* colors.

I could adjust the documentation for you if you want to added the light_* colors to the README.md, or did you want to do that, or did you want to just leave it as-is?

Figured I would open this up, as it would have saved me a bunch of time if they were in the list of colors.

A PR to adjust the documentation would be appreciated!

~~I suspect the reason I never properly documented the light_ foreground and background colours is that they aren't supported by all terminals.~~ They're also incorrectly named, and really should be called bright. These colours were added recently and copied the names used by the colorama library: https://github.com/borntyping/python-colorlog/issues/87.

Yes, pycharm uses the term Bright, and the non-bright white is grey.

Probably fine to keep them as-is so it won’t break anything.

I’ll try to get a doc change pr up over the weekend.

Sorry, have not gotten to this yet. I'll try to do it by end of week.

No rush - this library's been around a while, fixes like this aren't urgent :)
