Pico Display 2 examples ported.
Major change, the registers used before were incorrect, the x and y were swapped, the code I cribbed them from was wrong! Also implemented pressure (Z) as some screens give wonky results with light pressure. Pressure rejection to touch is on line 73 of xpt2046.cpp, currently set at 50% of max pressure. We also now have a pressure value for points (now TouchPoints), from 0-100 where 100 is max pressure.
Add TouchPoint struct. Add calibration for Z.
