Detailed Description

Remove crosstalk from a raw DECam Multi-Extension FITS file.

This must be done after the overscan is corrected but before it is trimmed.
NOTE: This version of crosstalk removal assumes you want to do it as an
standalone file operation, not as part of a regular stack-ISR workflow.
