This PR updates the rust bindings to ensure that we never pass OCaml-managed memory to rust functions. This guarantees that we do not read from OCaml heap memory addresses when objects may have been moved by the OCaml GC.
Performance in the interface is slightly worse due to increased copying, but better that than segfaults.
