Data from 2004 lacks POFFSET/QOFFSET header keywords & standardizeWCS() crashes

[DBerke]

GNIRS XD science frames S20041127S0110-117.fits don't have QOFFSET or POFFSET header keywords; those keywords are used to get detector_x_offset() and detector_y_offset() in AstroDataGNIRS, and without them the reduction crashes in standardizeWCS() in primitives_gemini.py due to trying to subtract two NoneTypes. (The flat, pinhole, and arc reductions all proceeded without issue.)
