+ Font draw speed and flicker test, draws all numbers 0-999 in each font
+ Average time in milliseconds to draw is shown in red
+ A total of 2890 characters are drawn in each font
+ 
+ Needs fonts 2, 4, 6, 7 and 8
+
+ Make sure all the display driver and pin connections are correct by
+ editing the User_Setup.h file in the TFT_eSPI library folder.
