Support `OrderedDict` and `OrderedSet`

[haberdashPI]

These two defy the expectation of the hash functions for Set and Dict objects. We should probably use https://github.com/cjdoris/PackageExtensionCompat.jl to implement a hash_method for these types that respects the ordering of elements.

Alternative, wait until Julia 1.10 is LTS, and use the extension feature. Probably best to implement for StableHashTraits 2.0 in that case (thus 1.* can be compatible with ≥ 1.6 and 2.0 with 1.10 and onwards).
