* fix: except only non-system-exiting exceptions see https://youtu.be/zrVfY9SuO64 * chore: add myself to CONTRIBUTORS file * refactor: explicitly specify possible exceptions If an exception is not an Exception, there are only three options left. see https://docs.python.org/3/library/exceptions.html#exception-hierarchy * refactor: use BaseException for fallback Co-authored-by: Damien Elmes <dae@users.noreply.github.com> * chore: add myself to contributors
