[Wien] finding density of states for individual bands

The problematic part is that while joint claims it can give you a DOS
for just one band (with the switch 2), this is actually not a DOS of a
single band but of a single band index. This will be the same thing
only if there is no band crossing (the difference will be obvious if
you do energy band structure plot with x spaghetti with and without
running x irrep before).

Best regards
