rust-index: add a `inner` method to the Index struct

We are about to introduce a Rust wrapper to the C index. It will be exposed as a
Python object. As a start all call will be forwarded to an internal index object
(as used now).

For this forwarding to works, we need to access that index object (from the C
extensions). We adds a method doing to on the existing `Index` rust struct.
