Generate colors for Alacritty (#33)

Needs review, still pretty rough.

Sorry for the long radio silence! I took a look at the PR and it already looks really good. I especially like that you take the selection colors from the actual theme.

There are a few missing directives which we should add with the first PR. I think we can take the hl_groups and convert them into a key/value table for easier access.

I also wouldn't take the primary foreground and background from the terminal colors and instead take them from the Normal HL group maybe? Since that's what the Vim/Neovim color scheme also uses.

Lastly, let's just stick with the provided colors for this PR. The terminal colors need an overhaul anyway. So I think it would make more sense to split it like this:

1. Add the templating function(s) to generate an Alacritty theme from the current colors
2. Overhaul the terminal colors in the actual color scheme, which should then automatically carry over to the Alacritty theme

Let me know how much time you have for this right now. I could also pick it up since I have a bit more time over the next 7 days.

That's right, Alacritty supports more directives, so we should try to add them:

• vi_mode_cursor
• search
  • matches
  • focused_match
• hints
  • start
  • end
• line_indicator
• footer_bar

Not sure if we need to provide dim colors, because Alarcitty will calculate them automatically based on the normal colors.

Could you please provide better understanding of hl_groups transformation to key/value table? You want to convert yui.lua -> M.groups?

Agree.

So yeah, let's finish with first point, then merge it. Colors overhaul will be in a different PR.

I have time in thees week also, so I can stick to it.

I'll start working on this now after my recent changes. I'll use https://github.com/alacritty/alacritty/blob/master/extra/man/alacritty.5.scd as the basis and add Theme:alacritty()
