Request: Export colors directly for selected variant

[madser123]

For some edge cases, colors would be nice to have as a variable directly from the catppuccin module.

I have a case where i need a color from the scheme to apply in a config for a span using pango-markup, and i don't want to hardcode it, as it then wouldn't change if i were to change the applied variant for the module.

Example usage could be something like:

{ catppuccin, ... }:
{
   usage = "${catppuccin.yellow}";
}

It would just be a nice QOL feature to have IMO 😄
