Consider supporting fswatch

[sharkdp]

We could probably support both inotifywait and fswatch as an alternative backend

Closing this in trying to clean my long list of open tickets. Feel free to comment here if you think that this is still relevant, so that the ticket can be reopened.

I'd definitely use this with fswatch!

I need this sort of thing often on my Mac, and I find entr pretty annoying to work with since I need to figure out the exact right way to feed files via stdin.

Really enjoy your other tools, specifically fd, bat and diskus, thanks for all you do! 👍

Thank you for your feedback!

I'm probably not going to work on this myself, but I'm happy to integrate fswatch support, if someone wants to work on this 👍

Implemented in #6
