	)

Deserializes the supplied (wire) buffer into an ack.

Parameters

packettype	returned integer - the MQTT packet type
dup	returned integer - the MQTT dup flag
packetid	returned integer - the MQTT packet identifier
buf	the raw buffer data, of the correct length determined by the remaining length field
