Cargo Audit in CI

Hi I am using `axoupdater` (thanks!) and since I run `cargo audit` in CI I was made aware of https://rustsec.org/advisories/RUSTSEC-2025-0004 because of your dependency on openssl.


Of course it is just a matter of updating a dependency for you as well, but it might be worthwhile for you to run an audit job in CI such that you are made aware of these issues as soon as possible.

Start by locating the repository's CI configuration and review how Rust dependencies are checked. Run cargo audit to reproduce the reported dependency advisory, then add a CI audit job that fails or reports on vulnerabilities; done means the check runs automatically for repository changes.
