dev: add code to have the proper data type when getting an AF table

- update BaseDataType to store the underlying type constructor e.g. int
- add helper functions to get the type constructor for constant data
- update operator graph to fill the type constructor during bounds update
- add loguru as logger
- use type constructor in ArbitraryFunction.get_table, log an info if the
type_constructor of the input was None and default to int
