Thank you for your contribution! Sorry it took a while for me to get to reviewing it.
I've left some review comments, but in general this looks like a good idea. (I'll also look into getting the CI working again, which would have at least caught the formatting issues).

Can we handle the "file not found" case here explicitly (by returning that the output needs to be updated)? Then we can also log a warning below if this function fails.

This comment still applies: Can you please explicitly check if fs::metadata returned "not found"?

Thank you for applying the changes, and sorry again for taking so long to review, things have been busy 😒.
Can you please rebase the branch on master? I've fixed the CI setup to run on Github actions now.
Optionally: It would be great to have an integration test for this. If you are interested, consider adding one in integration.bats.sh, otherwise let me know and I will add one.

This PR checks if the universal library is updated by comparing the mtime of it to the inputs.
If I am working on the non-rust part of an Xcode project, everytime I hit the run button
cargo-liporuns. In this case I expect thecargo-lipoto finish quickly since everything in rust is updated, but it takes noticeable time, because of thelipocommand. This PR solves this problem by doing a Makefile-style check before runninglipo.
