TwePacketIO

The TwePacketAppIO class interprets the standard app serial message (0x81) of App_IO The TwePacketAppIO class is the one that interprets the

class TwePacketAppIO : public TwePacket, public DataAppIO { ... };

Various information in the packet data is stored in DataTwelite after parse<TwePacketIO>() execution.
