For Python 3.11 a fix for how enums are formatted as strings

[Jared-Newell-Mobility]

See #447

There are still quite a few enums which subclass from (str, Enum). See

When running the tests in Python 3.11, the tests fail with:

tests/v201/test_v201_enums.py:1: in <module>
    from ocpp.v201.enums import ConnectorType, DataType, TxStartStopPointType
ocpp/v201/enums.py:1398: in <module>
    class PhysicalComponentName(str, Enum):
E   NameError: name 'Enum' is not defined
