Adding SPRKKR parser
I want to add SPRKKR. This is a Green's functions-based code which can work on LDA, GGA, LDA+U and DFT+DMFT for calculating dos (spin-polarized or not), transport, and mainly spectroscopic properties. They also have an interface from ASE2SPRKKR.
I talked with the main professor, Jan Minar, and he would be interested in using NOMAD as long as all the surfaces, impurities, and alloys are properly covered in System. I talked with him that this is our main goal now in harmonizing with other Materials Science areas of FAIRmat and he was happy to hear it.
I will organize a meeting soon, so we can both join and ask more directly about example cases to treat. I think on the development, we can add it as a parser plugin, instead of adding it in some project.
