Simplify model interface

[Kircheneer]

This is a draft of an attempt to simplify the interface for defining models a bit. Here is what an example model definition now might look like:

fromtypingimportAnnotated, List. Optionalfromdiffsync.enumimportDiffSyncFieldtypefromdiffsyncimportDIffSyncModelclassCity(DiffSyncModel):
_modelname="city"name: Annotated[str, DiffSyncFieldType.IDENTIFIER]
population: Annotated[int, DiffSyncFieldType.ATTRIBUTE]
classCountry(DebugModel):
_modelname="country"name: Annotated[str, DiffSyncFieldType.IDENTIFIER]
iso_code: Annotated[Optional[str], DiffSyncFieldType.ATTRIBUTE]
cities: Annotated[List[City], DiffSyncFieldType.CHILDREN, "city"] = []

Open points

• Evaluate, whether this breaking change (eyeing at 2.0) is worth it
• Documentation
• Think about further possibilites for simplification

I thought that this was only available in 3.9 and above? https://docs.python.org/3/library/typing.html#typing.Annotated

True actually, I didn't know. Should use this for compatibility

Closing for now.
