- Changed clipping for both magnitude and phase, not only magnitude - Added clipping functionality to stochastic engines (CPU and cupy) - Renamed .cu file to clip_object - Renamed functions that referred to magnitude clipping
- Added soft clipping to ML algorithm (CPU and cupy) - Added it to stochastic and projectional serial engines - Small cleanups

Fixed a couple of refactoring I had missed. Nonetheless, the latest test error on WASP_serial regarding the complex type of the object I am not sure how to solve yet. Running the WASP and WASP_cupu engines directly do not present this error |

The clipping input is now assumed to be either a 2-tuple or 4-tuple.
In case it is as 2-tuple, it is assumed to be (mininum_magnitude, maximum_magnitude)
In case it is as 4-tuple, it is assumed to be (mininum_magnitude, maximum_magnitude, minimum_phase,maximum_phase)
For ignoring a specific clipping, use None. For instance: (minimum_magnitude, None, None, maximum_phase)
I kept the approach that was already implemented for the magnitude clipping, so it is done right after object update and before probe update.
Done:
Still possible ToDos:
One open point of discussion: what is the "correct" way of doing such a clipping? Currently, we clip the magnitudes (np.abs) followed by clipping of the phase (np.angle), which would result in a behavior in the complex plane as the following:
