Title: Add mutable-value iterators to std::trie

- Add `mut_iter`, `mut_lower_bound`, `mut_upper_bound`
- Remove some internal iterators
- Add benchmarks
- Improve performance of `{mut_,}{lower,upper}_bound`
- Minor clean-up of `extra::treemap` after I realised I wasn't exploiting macros to their full DRY potential.
