Subject: [PATCH] Additional traits for Iter

Most importantly, Clone, which is generally useful (to pass it to
somewhere and iterate over it multiple times, but also for reverse
dependencies, see https://github.com/bodil/im-rs/issues/134).

Piggy-backing Debug when at it, because, why not.

*Not* implementing Copy, as that could lead to footguns (iterators
forking by accident would do confusing things).
