Returns z-address, viewing key, and optionally an extended secret key.

Arguments:
   "address"          (string, optional) z-address that is present in this wallet
   "seed"             (string, optional) raw wallet seed
   "hdindex"          (number, optional) address to derive from seed (default=0)
   "rootkey"          (string, optional) extended private key
   "fromid"           (string, optional) a key to be used between the fromid and the toid
   "toid"             (string, optional) a key to be used between the fromid and the toid
   "encryptionindex"  (number, optional) can be used as an index to derive the final encryption HD address from the derived seed (default=0)
   "returnsecret"     (bool, optional) if true, returns extended private key - defaults to false


Result:
{
  "extendedviewingkey" : "evk",            (string) "sapling" extended viewing key
  "address" : "encryptionaddress",         (string) The encryption address derived
  "extendedspendingkey" : "encryptionaddress", (string) Spending key for the address, if requested
