This PR updates the orchard crate to use a backward-compatible version of the halo2 crate. It contains two key changes:

Brings the LookupRangeCheck trait into scope (this maintains backward compatibility and allows existing code to function without additional modifications).
Updates Cargo.toml to point to the improve-backward-compatibility-without-zsa branch of the halo2 crate.

Note: This PR is a draft and is not intended to be merged. It is for review purposes only.
