Put DC2/HSC/DES data in NERSC for notebook documentation compilation

[m-aguena]

Should we put the data for the DC2/HSC/DES notebooks somewhere in NERSC/CC for easy compilation of documentation for the website?

Yes, that's be great. It's public HSC and DES data right, so there's no concern about hosting this small subset of data ourselves? I sort of remember @shenmingfu getting in touch with HSC to see if this was OK a while ago, but now everything is public...
