Use `noline` for line editing

[eivindbergem]

I'm the maintainer of a no_std line editor called noline. I'd like to use noline as the line editor for menu.

With noline you get:

• Proper ANSI terminal line editing with arrow navigation and emacs-style keybindings
• Sans IO core, supporting both sync and async
• Generic over storage buffer, can be static or heap allocated
• Line history

I need menu for a work project, so I have time to do the integration. This might cause some breaking changes to menu, so I'm checking if this is something that you're interested in. If not, I'll just make a fork, so no worries.

This sounds very cool, but can we make the integration optional - for anyone who is happy with it as it is?

Sure, we could put it behind a feature gate :)
