MapDiffer<K, V> class Null safety

Determines differences between two maps, returning MapChangeRecords.

While MapChangeRecord has more information and can be replayed they carry a more significant cost to calculate and create and should only be used when the details in the record will actually be used.

See also EqualityDiffer for a simpler comparison.
