(expression has type "Optional[IanaCountryTldEnumeration]", base class "EntityStructure" defined the type as "Optional[str]")

Generate base type for enums

It's way to tricky to handle these cases, the enum converter will need a lot of hacking and we will have a tone of issues with mixed type enumerations. I am thinking that for these cases we should ignore the subclass override type annotation.
