Add colour/unicode/emojis to `cabal check`

One of the ways to figure how to do it is to steal from someone, i think. E.g. cargo would be my first choice to look for an example. I guess, I could look into what Julia and its package manager do in such cases. I just need to figure out what would be the closest scenario…
