naco_spc_lampflat -- NACO spectrocopy flat-field creation from lamp images.

The files listed in the Set Of Frames (sof-file) must be tagged: NACO-raw-file.fits CAL_FLAT_SPEC

The input frames are split into groups with identical values of 'ESO DET DIT', 'ESO INS OPTI1 ID', 'ESO INS CWLEN' and 'ESO SEQ SPECMODE'.

Furthermore, the input set of frames must have values of the FITS key ESO INS LAMP2 SET that of zero for off-frames and non-zero for on-frames.
