Use DFT to insert Focal Plane Mask.

Pupil convolution by complex focal plane mask of limited support typically used with fpmz = zoomed copy of 1-fpm

High resolution focal plane mask using DFT

Forces computation over pixels >0.5 in _DFTmask00 if it exists

Warning

This internal test could crash the process as multiple write operations to the same filename may occurr: leave option OFF for production
