rust-pkcs11 dependency is unmaintained

[ddiss]

Thanks a lot for publishing your interesting project. While looking into a aarch64 cross-compilation issue with the libloading nested dependency, I noticed that rust-pkcs11 is flagged as deprecated upstream via https://github.com/mheese/rust-pkcs11/commit/ab4c79a0bc56e4d97b5b30a2d2b68031d0a26036 . Are there any plans to rebase against rust-cryptoki or an alternative?
