Breaking changes:
resize no longer drops bindings if the new size pushes the queue over capacity.of_list has simpler semantics; dropped the cap parameter.Other changes:
Lru.M.cache with more general Lru.memo.trim to shrink a queue to its capacity, as queues are no longer guaranteed to have size smaller than capacity.find gets the promote parameter, allowing queries that do not change the order.add gets the trim parameter, allowing insertions that do not drop old entries.
