We are refactoring away from a single rust with wasm_bindgen taggings directly, over to a dedicated rust crate(s) and a separate wasm bindings crate, which should vastly improve usability from rust as we don't need to conform to the limitations of wasm_bindgen. While this is happening we will take advantage of improvements to cddl-codegen to introduce CBOR encoding tracking.

Once this is done we will delete the existing crate in rust/ and use the rust/core/ and rust/wasm/ bindings.

There may be additional crates depending on how things are organized.
