cargo udeps

Use https://github.com/est31/cargo-udeps to check if all dependencies are used

It would be cool if this action could, for each unused dependency found, open a PR that removes it!

We would love to use such action. Does anyone have experience running cargo-udeps in a Github action?

There has been some recent work by @aig787: https://github.com/est31/cargo-udeps/issues/68#issuecomment-812768641

If there's interest, I'm happy to transfer ownership of the repo over. The action itself is very similar to https://github.com/actions-rs/tarpaulin, just with slightly different artifact download logic.

I figured out a manual way to do that if you are interested.
