feat: add a public Range.iter() method (#18) (pubgrub-rs#187)

Co-authored-by: Zanie Blue <[email protected]> Otherwise, it's not possible to implement custom formatting of `Range` types. This seems generally useful to expose. Example usages: https://github.com/astral-sh/uv/blob/8d721830db8ad75b8b7ef38edc0e346696c52e3d/crates/uv-resolver/src/pubgrub/report.rs#L97-L112 https://github.com/astral-sh/uv/blob/8d721830db8ad75b8b7ef38edc0e346696c52e3d/crates/uv-resolver/src/pubgrub/report.rs#L549-L560 https://github.com/astral-sh/uv/blob/8d721830db8ad75b8b7ef38edc0e346696c52e3d/crates/uv-resolver/src/pubgrub/report.rs#L568-L605 Upstream port of #18, but `impl Iterator<Item = (&Bound<V>, &Bound<V>)>` instead of `impl Iterator<Item = &(Bound<V>, Bound<V>)>` to avoid constraining it to a tuple.
