Add Wannier90 parser
I worked in the parser and metainfo for Wannier90. I included a new Method, called `Projections`. This code uses DFT sfc calculation as input, and outputs the _projected_ bands into some localized and virtual orbitals (Wannier orbitals). These projected bands can be then used to do further many-body calculations (e.g., DMFT, HF, RPA, etc). TODO: - [ ] Add metadata for TimeRun. - [ ] Include workflow_ref to the DFT calculation. - [ ] Check with the input DFT calculation if energy_fermi is correctly defined (currently it is extracted from the Wannier90 input file).
