Add test and input for simple_sweep_2.ifc; extend constructor for sweep_along_curve to support fixed reference swept area solids

Browse Source 
Includes `simple_sweep_2.ifc` test input, geometry validations in `test_sweeps.py`, and a new constructor for `sweep_along_curve` to handle directrix-based sweeps.
