Add ESP32 VSPI or HSPI port option + others

Browse Source 
If the VSPI port is in use and pins are not accessible (e.g. TTGO
T-Beam)
then add or uncomment the following line in the setup header file:
//#define USE_HSPI_PORT

Minor performance tweaks for ESP32 to minimise the occurence of the slow
transaction overhead.

setAddrWindow now takes xstart, ystart, width and height as inputs

Multi-sample raw touch x and y for noisy displays

Example update for setAddrWindow change compatibility
