count-to-non-zero 0.3.0

Extends Rust's Iterator trait to include a `count_to_non_zero` method, returning an Option<NonZeroUsize> for a more expressive and type-safe way of counting elements. This crate provides a convenient and idiomatic approach to obtaining non-zero element counts from iterators, enhancing code readability and safety by leveraging Rust's type system. Perfect for applications where distinguishing between empty and non-empty iterators is crucial, without the overhead of manual count checks.
