Add CI tasks

[Acaccia]

This PR adds some CI to the repo:

• on each new PR against main, we run the tests, check formatting and check for the absence of clippy warnings
• on each push to main, same checks
• on change in Cargo.toml or Cargo.lock, we run cargo-audit
• every day, we run cargo-audit and check for clippy warnings (in case there would be new ones after a toolchain update).

Closes #12

I think this needs the merge of #15 which fixes formatting and clippy warnings.

Yeah if you based it on #15 then I fixed a bunch clippy stuff + fmt waiting

Yeah, it's helpful to auto-generate changelogs and to determine release versions numbers.

I went ahead and enabled the check that the be required to pass before PRs can merge into main.

I always agree with commit conventions. I sadly did not now we were following one on this repo.

This should be in the Readme or a CONTRIBUTING.md file. And in this case, we should also describe the possible types and scopes.

Woohoo, these checks are working great! 🎉
