Input: wacom - 3rd gen Bamboo P&Touch packet support
3rd generation Bamboo Pen and Touch tablets reuse the older stylus packet but add an extra fixed zero pad byte to end. The touch packets are quite different since it supports tracking of up to 16 touches. The packet is 64-byte fixed size but contains up to 15 smaller messages indicating data for a single touch or for tablet button presses.
