Rewrite ModelBindingsMapper to more efficiently handle parallel lists

[kevinstadler]

Mapping this query result onto the following flat model takes the mapper ~20 minutes at 100% CPU, even though the 9840 query result lines actually all get mapped to a single result object (see below).

from typing import Annotated

from pydantic import AnyUrl, BaseModel, Field  # noqa: F401
from rdfproxy import ConfigDict, SPARQLBinding


class Person_PersonAppellationAssertion(BaseModel):
    model_config = ConfigDict(
        title="Name(s) in the sources",
        model_bool="id",
    )
    id: Annotated[
        AnyUrl | None, SPARQLBinding("person__person_appellation_assertion")
    ] = Field(default=None, exclude=True)
    person_appellation_is: Annotated[

        SPARQLBinding("person__person_appellation_assertion__person_appellation_is"),
    ] = None

        model_bool="id",
        group_by="id",

The correct single result which is eventually returned (the underlying GraphDB query result has 9840 lines because it shows every possible permutation of the 41*8*6*5 contained list items):
