HPA_DCO_1 - Add HPA, DCO capability

Browse Source 
1. nwipe now reads the HPA set and real number of
sectors and the DSO real max sectors. It determines
from these values whether the HPA is enabled, disabled
or in a unknown state. The values are logged to nwipes
log and flags are set in the drives context.

More code will follow that adds this information to the PDF
certificate and to the drive selection window in the GUI.
