Update cast crate, remove cargo-deny rules (#2909)

Previously the inclusion of the `criterion` crate had brought in a
transitive dependency to `cast`, which used old versions of several
libraries. Now that https://github.com/japaric/cast.rs/pull/26 is merged
and a new version published, we can update `cast` and remove the
cargo-deny rules for the duplicated, older versions.
