save profiles in FITS format #1261

Currently profiles (spatial, spectral, stokes, histogram) can be exported as tsv format. Users request to support FITS format too so that it is easier for post-processing with other tools (eg chemical modeling).

The actual generation of the FITS file can happen at the frontend or the backend. TBD.

can you provide an example FITS file with the correct headers and content?

Here are two examples from SDSS. spectra_fits.zip I suspect there is no such standard for 1d spectrum.
