Conversion factors are now stored in the FITS headers using the JYPXFACT keyword
Slight change to the comment for JYPXFACT. Note that conversion factors are no longer being printed to the terminal, but I have kept the output_conversion_factors() function just in case we still need something in it.
The FWHM value is now being stored in the FWHM header keyword during the convolution step.
