Request: bind ctrl+q to quit

[AndydeCleyre]

Is your feature request related to a problem? Please describe.

I have a function which uses fzf, skim, or gum choose, depending on what's available on the system. In fzf, ctrl+q quits, and I can bind the same when launching skim. I'd like ctrl+q to act the same way with gum, so I don't have to think about which tool is being used.

Describe the solution you'd like

Either: bind ctrl+q to quit, at least during gum choose, as I don't think it's bound to any other action,

Or: implement configurable keybinds

Describe alternatives you've considered

Building muscle memory to use ctrl+c (interrupt) for all three tools.

Additional context

I would expect exit code 130 in this case.
