tui option

[unorsk]

Hey! I really love zigup and I have been using it almost everyday for the past week :) There is a similar tool in the Haskell ecosystem ghcup and it has a tui option (which I like a lot) And it looks like this

So I was wondering if having something like this would be welcome (I'm willing to make a PR). I've played a little with zigup in my fork and I think I could make it work :) Here is what it could potentially look like

ps Unfortunately doing this without libvaxis seems like a lot of work. Would adding this one as a dependency work for you?
