add option to update energies of some levels to v accurate values
Peter pointed to ths paper as a source for some IR wavelength: https://articles.adsabs.harvard.edu/pdf/1993A%26A...274..662R Chianti and Stout have different sources with don't agree with JWST. We cannot had edit Chianti or Stout since the info would be lost upon the next update. We could add a ancillary file with "better" energies for some levels and use those preferred levels rather than the database entries by default. Have a user option to not do this
