Consider allowing windowsHide option

[jabrown85]

See nodejs/node#29837 for why this option can make a practical difference. I saw the previous discussion on #242 that was closed because there wasn't a known reason to allow it.

Hi @jabrown85! Thanks for filling this issue.

Yes that makes sense.

TLDR: without windowsHide: false on Windows, CTRL-C does not work. So we should still default it to true but allow users to override it to false.

@sindresorhus what do you think?

Sure, as long as we clearly document in what specific scenarios it might be useful.
