CpFringeTask

CpFringeTask preprocesses the input exposures to prepare them for combination into a master fringe calibration.

Processing summary

CpFringeTask runs these operations:

1. Divides the input exposure by the measured background level, normalizing the image sky to 1.0.

2. Finds all sources above the masking threshold, and masks them
