Non-zero exit status 3

Using pdf-sign file.pdf, I receive the error below. I haven't run into this before the new version (maybe when pdftk was used?). Seems to be for only some files.

@GregorySchwartz Would be great if you could provide 1) An example problematic file without sensitive content and 2) The nix flake producing ic3q5cr8jx5ghwhw2k8sccvn6dhd2jzj or versions for pdf-sign and qpdf.

@GregorySchwartz Bump. An example file might be enough.

Unfortunately the only files I could reproduce this with have sensitive information...

[svenssonaxel]

@GregorySchwartz Could you please test branch dev?

1. Executing as before, you should see the same warnings, but no traceback. pdf-sign should print qpdf exited with code 3, indicating warnings. Use --continue-on-warnings to ignore. and exit with code 1.
2. Adding --continue-on-warnings to the invocation should cause pdf-sign to function normally, except the warnings should still be printed.
