Gum Spin pin to the bottom

[snallapa]

Is your feature request related to a problem? Please describe.
I found that gum spin always stays in one place, so if the command has a lot of output that is informative, it will mask the spinner.

Describe the solution you'd like
It would be nice if the spin was pinned to the top or bottom and still show commands output when the command output is informative to the user

Describe alternatives you've considered
right now all you can do is hide the output or show the output. maybe it would be good if for example you only showed the output when the command failed?
