Jitter has already been added but there is no keyword from the .ini file to setup the jitter in mas at the moment.
- Consider setting jitter from config.keys()
- Add a class attribute called 'jitter' in either the system or ParametricPSFfromPSD to call
self._otfJitterin the psfmodel.py
Same for the custom pupil and phasemask
- Consider setting the path of the pupil and the phasemask from the config.keys
