ProjwfcCalculation Doesnt doesnt parse properly pdos_tot (Bug)

[AndresOrtegaGuerrero]

When using a spin polarized calculations , the Calculations doesn't parse pdos_tot file appropriately
instead it saves in 'y_array_0' the dos_up, and it doesn't parse the dos_down column

Thanks @AndresOrtegaGuerrero for reporting. Indeed, we somehow only parse the first column:

aiida-quantumespresso/src/aiida_quantumespresso/parsers/projwfc.py

Lines 319 to 325 in b79189d

	try:
	pdostot_filename = fnmatch.filter(out_filenames, '*pdos_tot*')[0]
	with self.retrieved.base.repository.open(pdostot_filename, 'r') as pdostot_file:
	# Columns: Energy(eV), Ldos, Pdos
	pdostot_array = np.atleast_2d(np.genfromtxt(pdostot_file))
	energy = pdostot_array[:, 0]
	dos = pdostot_array[:, 1]

Intuitively, I would also think that we'd need some spin-dependent logic here, since I don't see a reason why we should only parse DOS up (maybe it was sufficient at that time as the DOS is calculated via dos.x in the WorkChain anyway, just speculating). Nonetheless, pinging @mbercx to see whether there is any historical context.
