This program applies a flat-field correction for each framelet based on the
band's filter number. In order to output in I/F units, the cube must have spice
data. This calibration problem follows the algorithms described the document titled:

Added lookup table
Fixed a problem where segmentation faults would occur if run
with the option "IOF=false"
Added code to obtain exposure times from $mro/calibration/marci/varexp.tab
so they can be used when calibrating the input image. Also had to handle
images that have been flipped by marci2isis. Fixes #1860.
Fixed a bug in exposure time accounting. Fixes #1860.
Modified to use the exposure duration from the new label keywords added by
marci2isis. Related #2034
