Update GFALL data and/or parser

[isaacgsmith]

There is new GFALL data that has been released since 2016 (see http://kurucz.harvard.edu/linelists.html under GFNEW). I tried parsing it with carsus but it did not work, so I am assuming that the parser either needs to be updated, or something needs to be done with the .dat file to make it readable by carsus. I am not sure which one of these is the case, since I am not too familiar with carsus.

I am including my error message when parsing gfnew/gfall08oct17.dat in case it is helpful:

Or maybe we need to write a new parser, I don't know how similar the file is
