Added support for Touch input

Menu System for Adafruit_ILI9341 displays with touch or mechanical input

This library will simplify creating and implementing a menu system for TFT displays that use the Adafruit_ILI9341 displays with microcontrollers such as the ESP32. See my other repository for the ILI8341_t3 for Teensy-based projects.
This library includes two menu objects

A simple selection menu (ItemMenu) where the user can scroll up/down and select an item and some programmer defined action can be performed such as drawing a screen or activating a sub menu
A menu with in-line edit capability (EditMenu) where the user can scroll up/down the list and select an item however, the difference is that move/up down on a selected item will then scroll the values stored with that menu item, selecting a selected item will restore control to moving up/down the menu list

To activate touch usage specify true in the menu object creation step

EditMenu(Adafruit_ILI9341 *YourDisplayObject, true);
ItemMenu(Adafruit_ILI9341 *YourDisplayObject, true);

To activate mechanical input usage specify false (default) in the menu object creation step

EditMenu(Adafruit_ILI9341 *YourDisplayObject, false);
ItemMenu(Adafruit_ILI9341 *YourDisplayObject, false);

While this library was created for Adafruit_ILI9341 drivers, the library can be adapted to other display drivers. Note the driver must use the Adafruit_GFX libraries. To allow other display drivers, modify the lines in the .h and .cpp files to allow a different driver to be passed in. For example change call such as SliderH(ILI9341_t3 *disp,... to SliderH(Adafruit_RA8875 *disp,... and in the .cpp files you may have to change how fonts are passed in using either setFont(&SomeFont) or setFont(SomeFont)
