[mypy] Incompatible types in assignment

[foarsitter]

Thanks for providing this extension, it makes working with xml fun again.

The from_* methods are typed against BaseXmlModel which results in an mypy error.

message: Message | None = Message.from_xml(xml)

error: Incompatible types in assignment (expression has type "BaseXmlModel | None", variable has type "Message | None")

Pydantic itself uses a TypeVar bound to BaseModel so children are accepted as return type.

Is this something you want to support? If so, I can submit a PR.
