Description

Remove the incorrect determination of spectral line and replace it with the dkist-spectral-line library implementation.

  • Remove “spectral line” (actually filter) list and places it was used (parsing, Write_L1)

  • Populate @abstractmethod in the Write_L1 task to determine the wavelength range of a VISP frame

  • Update unit tests to ensure spectral line determination is working

For units, an example from VISP data we have currently has

CRVAL1 = 854.231 CDELT1 = 0.000999811469978602 CRPIX1 = -25.29957916079859 NAXIS1 = 2539

These values (specifically CRVAL and CDELT) imply units of nm.
