✨ Increase number_of_types to 5 to support longer select queries

[GiorgioPorgio]

I am trying to write a select statement that selects 5 different SQLModel children. However I get a type error as the overloads for select are limited to 4.

Increasing to 6+ causes mypy to hang, so I chose 5 :)

Resolves #271 (comment)

Thank you very much for your time and working on OSS!

Just as an idea:
what if we introduce a rule that all _TScalar_XX should go before any of _TCCA[_TXX]?
This way we only need to add 7 overloads for the 5 parameters, 8 overloads for 6 parameters, etc..

See example for 5 parameters in the details:

@overload
def select(  # type: ignore
    __ent0: _TCCA[_T0],
    __ent1: _TCCA[_T1],
    __ent2: _TCCA[_T2],
    __ent3: _TCCA[_T3],
    __ent4: _TCCA[_T4],
) -> Select[Tuple[_T0, _T1, _T2, _T3, _T4]]: ...


@overload
def select(  # type: ignore
    entity_0: _TScalar_0,
    __ent1: _TCCA[_T1],
    __ent2: _TCCA[_T2],
    __ent3: _TCCA[_T3],
    __ent4: _TCCA[_T4],
) -> Select[Tuple[_TScalar_0, _T1, _T2, _T3, _T4]]: ...


@overload
def select(  # type: ignore
    entity_0: _TScalar_0,
    entity_1: _TScalar_1,
    __ent2: _TCCA[_T2],
    __ent3: _TCCA[_T3],
    __ent4: _TCCA[_T4],
) -> Select[Tuple[_TScalar_0, _TScalar_1, _T2, _T3, _T4]]: ...


@overload
def select(  # type: ignore
    entity_0: _TScalar_0,
    entity_1: _TScalar_1,
    entity_2: _TScalar_2,
    __ent3: _TCCA[_T3],
    __ent4: _TCCA[_T4],
) -> Select[Tuple[_TScalar_0, _TScalar_1, _TScalar_2, _T3, _T4]]: ...


@overload
def select(  # type: ignore
    entity_0: _TScalar_0,
    entity_1: _TScalar_1,
    entity_2: _TScalar_2,
    entity_3: _TScalar_3,
    __ent4: _TCCA[_T4],
) -> Select[Tuple[_TScalar_0, _TScalar_1, _TScalar_2, _TScalar_3, _T4]]: ...


@overload
def select(  # type: ignore
    entity_0: _TScalar_0,
    entity_1: _TScalar_1,
    entity_2: _TScalar_2,
    entity_3: _TScalar_3,
    entity_4: _TScalar_4,
) -> Select[Tuple[_TScalar_0, _TScalar_1, _TScalar_2, _TScalar_3, _TScalar_4]]: ...


@overload
@deprecated(
    """
    This version of `select` function is deprecated.
    You should order parameters so that all `_TScalar_XX` parameters would go before any
    of `_TCCA[_TXX]` parameter.

    Read more: [link to the documentation]
    """
)
def select(  # type: ignore
    __ent0: _TCCA[_T0],
    param_1: Any,
    param_2: Any,
    param_3: Any,
    param_4: Any,
) -> Select[Tuple[_T0, Any, Any, Any, Any]]: ...

Last overload is to catch the wrong parameters order and show the deprecation warning with clear message and link to the docs.

We can leave overloads for 1-4 parameters as it is for backward compatibility, or optionally mark overloads that don't follow this rule as deprecated.

Increasing the limit from 4 to 5 means this problem will happen again when someone has a select with 6 inputs. I'm not familiar with the code at all, but is there some way to accept an arbitrarily large number of inputs? Or increase the limit to something absurd like 50?
