This PR introduces a number of changes to the radonfourier cuda implementations based on discussions in #611
Those changes improve the speed of both the 2D and 3D implementations (see https://github.com/PyLops/pylops_notebooks/blob/master/developement-cupy/Radon-Fourier.ipynb):
2D: forward 10.2ms, adjoint 11.2ms --> forward 2.5ms, adjoint 2.4ms
3D: forward 9.8ms, adjoint 6.1ms --> forward 3.1ms, adjoint 1.65ms
I would like to get this changes in before moving on to adding the grid-strided loops (#616)
