Error with python3.11

[martin3000]

Running HA with python3.11, I get this error.
See https://docs.python.org/3.11/whatsnew/3.11.html#dataclasses
Maybe adding a __hash__ method will fix it.

[martin3000]

This hack fixed it for the moment. I added it to the classes GoodInput, GoodOutputA, Port and ArtIpProgCommand

    def __hash__(self):  # jms
        return hash(123456789)

    def __eq__(self, other):
        return (
            self.__class__ == other.__class__
        )

I think a more proper fix is as such:
