Update FPS_GT511C3.cpp

Updated logic  of Response_Packet::ErrorCodes::Errors_Enum Response_Packet::ErrorCodes::ParseFromBytes(byte high, byte low) to set error code for any non-zero high byte.  Also updated comment in Verify1_1 to indicate default return value is set before error codes are checked.
