Last Hawk band (233) always blank in level 1

[benj]

The last band of Hawk data files processed to level 1 (band 233) always seems to be blank. Happens processing through both azspec and Caligeo so it's unlikely to be a software issue. I initially thought it was probably a band configuration issue but we're not using separate configuration files for processing, the calibration file in use covers a wider range than the data file and the band list in the header files is correct.

Not the end of the world because we advise against using bands at the edges of the spectral range of the instruments anyway (because they're generally poorly calibrated), but still not good.
