Future fix - Implement Union[int, float] for configclasses.RangeSubFIlter

[BuongiornoTexas]

Pydantic will convert integer values to floats as part of constructor input validation. The range_clause method will try to convert integer values back to integer form before generating the range clause. A future update may address this issues - requires pydantic to support dataclass validators (0.24+?). When this functionality is available, convert the type of ranges to List[List[Union[int, float]]] and add an appropriate validator.
