Hey,

I've been loving kor so far (especially how it returns dicts with raw, errrors and validated data).
But is there some way to create your own "types" with validators with pydantic 2 e.g.:

PhoneNumber = Annotated[
    str,
    AfterValidator(lambda num: ''.join(x for x in num if x.isdigit())),
    Field(
        description="Phone number in E.164 format",
        examples=["505505505"],
        min_length=9,
        max_length=9,
    ),
]

It would be quite useful for extraction tasks.
For now I've been kinda creating 2 models - 1 for kor which just gets strings, and 2nd to create more strict that validates the previous model, which is not ideal, but gets the job done.
