Add HC560 to db (WUH722020ALN604)

[Travis Norton]

Hi,
I'm working at Western Digital and would like to get a drive add to your database.

{"Western Digital Ultrastar DC HC560", // tested with WDC  WUH722020ALN604/PQGNW108,
  "(WDC  ?)?WUH722020AL[EN]6[0L][014]",
  "", "",
  "-v 22,raw48,Helium_Level "
  "-v 82,raw16,Head_Health_Score "
  "-v 90,hex48,NAND_Master"
}

Sample output lacks attribute 82:

...
 22 Unknown_Attribute       PO---K   100   100   025    -    6553700
 90 Unknown_Attribute       P---CK   100   100   001    -    304942678016
...
