This PR fixes #11 by using the poll() function.

Wow! I didn't expect this to be quite so straight-forward. I think I'd have probably made it far more contrived if I tried implementing it. Had no idea you could just batch up a bunch of file descriptors and poll them together in a single call... I'm not much of a RTFM type 😬

Thank you!

(Really should remove the binary from this repo and add it manually to releases, I tried to get CI to cross-compile for RPi but it's an absolute nightmare)

Heh, no problem. No expert here, I just RTFM 😅

Yes, the binary is small though and I committed it in case ppl would want to try it themselves. I usually don't mess with the github build server and instead use the gh command line tool to upload releases.
