add cargo semver-checks to CI

[plebhash]

As suggested by @Fi3 here: #766 (comment)

I would add something to automatically check the we do not mess with semver (it is very easy to think that something do not change the API but it change it). I found this linter https://crates.io/crates/cargo-semver-checks that we could add to our actions. That ofc do not remove the needs for human reviews is just an helper.

I'm trying to run it manually before I automate it into a Github Action. There are some issues, however:
