Crate arrow_cmp 

Basic comparator factories shared by Arrow crates that need to compare arbitrary array slots without pulling in the full arrow-ord crate.

The only public surface is make_comparator (with DynComparator as the returned function type). arrow-ord re-exports both from here, so its public API is unchanged.

This crate exists so that crates such as arrow-select can use slot-wise comparison (e.g. for the run-end-encoded take fast path) without taking on the full ordering kernel suite — which would either create a circular dependency (arrow-ord already depends on arrow-select) or force every downstream user of arrow-array to compile the comparator machinery whether they need it or not.

If parent sort order is descending we need to invert the value of nulls_first so that when the parent is sorted based on the produced ranks, nulls are still ordered correctly
