structdiff

Changes in this release:

• Added the ordered_array_like collection strategy, which uses levenshtein distance to create changesets for ordered collections
• Fixed a case where generated setters would not update the base struct when combined with a collection strategy

This release adds two changes to increase performance of diffing collections:

• size hints are used internally to decrease amount of time spent allocating (~5-8% faster according to in-repo benchmarks)
• rustc_hash is added as a (feature gated) dependency for cases where a non-cryptographic hash is acceptable (~50-60% faster according to in-repo benchmarks)
