Refactor/components

[lgiacome]

• We add some specialized components inheriting from the Component class that replace some of the utilities functions. The functions are kept for backward compatibility but they simply return the new specialized components
• Wherever the exponents tuple is given we add also the source_exponents and test_exponents tuples and a new function checks that two approaches are not mixed. The preferred approach should be to pass the two separate tuples.
• We move the dataclasses to a new interface_dataclasses module to avoid circular imports
