Remove methods that allocate, prefer iterators instead

[luizirber]

#3047 will need a new version bump, bringing in these changes because they also need a version bump

• Remove sketches method from Signature, use iter method instead -> core: find replacement for .sketches()? #2977
• Remove mins method from MinHash, use iter_mins method instead
• Add benchmarks for jaccard and count_common
• add_many takes an iterator now, similar to remove_many
• Add size_hint for Intersection iterator
