disable registration of 5 item map concrete class (is this safe on all platforms?) and add add check for class equivalence after serde rountrip
add test for map with 5 items (since  we removed the specific serializer for this small map)
remove commented line
register HashSet and HashMap concrete traversable instead of Set and Map (beyond specialized small size sets and maps). make sure to add the tests back in for registered map of size 5 (m5). add testing for class equivalence after serialization/deserialization roundtrip where applicable
