0.2.20.1

• Fix infinite loop in isSubmapOf[By] / isSubsetOf on 32-bit platforms.
  To fix this bug and potentially other similar bugs, we return to a branching factor of 16 on 32-bit platforms.

• Relax bounds for GHC 9.12

• Require hashable >= 1.4

• Documentation changes:

  • Fix documentation about branching factor in Data.HashMap.Strict
  • Improve documentation for Data.HashMap.compose
  • Fixes docs of Data.HashMap.Lazy.fromList: it takes O(n * log(n))
  • Add disclaimer to Data.HashSet.toList

• Remove bad isSubmapOf testcase
