spinner isn't always cleared from the screen

[daylinmorgan]

When running nimble -v there is a leftover working <spinner>.

$ nimble -v

relatedly when using nimble list --ver the spinner interrupts the output

It also makes it really hard to debug things as it's constantly clearing the last line.

@elcritch Is there a way for you to reimplement this without it being so obstructive? Perhaps you should disable it entirely in debug builds, whilst you're at it.

Makes sense, I'll look into clearing those up when I get back to some Nimble PRs.

It only clears lines with the spinner on them.

Adding an option to disable it for a build would be pretty simple change. I'm sure you could make a PR for that.

It would also be nicer (but not necessary and I imagine non-trivial with the existing nimble log output setup) for the spinner to actually spin by using a different thread.
