Fixed bug in RAAR

Fixed bugs in phase.py

Added argument dim to JWST_in, was required by ProxOperators

Added ProxOperator P_amp

Added ProxOperator Approx_P_JWST_Poisson: still needs to be tested

Changed comments in JWST_in and deleted duplicate
Modified Phase_JWST_demo.py to test phase.py

JWST_data_processor is now using the right Resize function from Utilities, norm_rt_data now matches norm_rt_data from the matlab version,
but other values still need to be checked.

Continued fixing JWST_data_processor, but JWST_data_prcessor is still not working correctly

Moved and renamed phase test script script.py
Made some progress on JWST_data_processor

Added FFT in Utilities/Utilities.py , FFT was tested and should work like the equivalent in the ProxMatlab.
But there are still issues with row-major order vs. column-major order, therefore implementation might not be efficient.
