Fix CC/CR/CV set and query commands to use correct syntax

Browse Source 
The manual's pipe symbol (|) means OR - e.g. CC|CURR:HIGH means use
either "CC" or "CURR:HIGH" as the command. The combined form "CC CURR:HIGH"
was not being parsed correctly by the device for queries. Now using the
second form (CURR:HIGH, RES:HIGH, VOLT:HIGH) which works for both set
and query operations. Verified readback works: set 1A -> reads 0.9999A.
