Make full spectra data files public

[karllark]

The full spectra are large and not well organized. And located only on central storage in many subdirectories. Jeremy and I have been talking about the need to get them more organized and posted publically. I will work on how to do this in manageable chunks. I'm currently thinking of having separate files for the 'discrete' variables (e.g., dust grain type, star formation type) with all the continuous variables for that set of discrete variables in one file (e.g., tau, sfr). Does this sound like a reasonable organization?

If we keep the param_table6_combined.tsvx file somewhere, I'm fine with splitting the .fits files based on discrete variables. The function to get the spectrum from ID number will have to be adjusted.
