feat(ffi): Export more derivable traits

[Alex6323]

Forwards some utility traits to the bindings by deriving them from the inner core type and exporting them. uniffi supports trait exports as mentioned here https://mozilla.github.io/uniffi-rs/latest/types/uniffi_traits.html

Closes #322 , but there's no point in not exporting other traits as well if we can to match as closely as possible the convenient Rust API for bindings users, so I'll do that as well.

Not sure why yet, but Ord (supported according to the docs) doesn't work.

Also fixes #433, which is necessary to make the CI pass.
