This PR updates the orchard crate to use the generalized version of the halo2 crate (link). 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.
