Add option to suppress ringing in Saturation Recovery script

Browse Source 
A parameter option "suppress_ringing" has been added to the Saturation Recovery script. This option modifies phase lists and allows the application of a phase cycle that compensates for ringing but reduces signal-to-noise ratio by half. This gives users the option to prioritize either reduced ringing or higher SNR as per their requirements.
