Type TAllowedParameterValue more completely #669

Currently, the type definition of TAllowedParameterValue is

TAllowedParameterValue = Union[
    str,
    int,
    float,
    datetime.datetime,
    datetime.date,
    bool,
    decimal.Decimal,
    None,
    list,
    dict,
    tuple,
]

list, dict, and tuple are incomplete types. That means when I try to write a wrapper function around cursor.execute using that type as the type of a parameter sql_params_dict, pyright strict yells at me Type of parameter "sql_params_dict" is partially unknown.

I think this can easily be fixed. My guess is, this could simply be a recursive type definition, and those last three lines could be changed to

    list[TAllowedParameterValue],
    dict[TAllowedParameterValue, TAllowedParameterValue],
    tuple[TAllowedParameterValue, ...]
]

However, there may be more or fewer restrictions on those types. I didn't look into it very hard.
