Serializing nested dataclasses using rest_framework.serilaizers.Field subclass about djangorestframework-dataclasses

[oxan]

Ah, this happens because if a field is of a dataclass type, it is expected that it's always serialized using DataclassSerializer. I should probably remove that assumption, but that's not entirely trivial (consider e.g. list[SSN], which needs a ListField with a SSNField inside of it).

Add another condition to check whether you have a Field mapped to the dataclass inside serializer_field_mapping and this field would pass the next condition: isinstance(field, Field) and not isinstance(field, Serializer), idk
