Modify payload command for tinytuya

pytuya supported two commands ("status" and "set"). For status, the higher level status()
method is used, which still works. But for set, in order to set multiple dps at once,
the lower level generate_payload method is used, passing in the commands. But tinytuya
has changed to use int commands defined as constants: AP_CONFIG, CONTROL, STATUS,
HEART_BEAT, DP_QUERY, CONTROL_NEW, DP_QUERY_NEW, UPDAtEDPS are the new commands, with
some differences for devices with 22 character IDs.  Equivalant of "status" is DP_QUERY
and equivalent of "set" is CONTROL, though some devices may need DP_QUERY_NEW and
CONTROL_NEW by the looks of the protocol (it does not appear that tinytuya handles this
automatically, unfortunately).
