Missing setupx_ ILI9486.h for Wemos D1 R32 with a 3.5"tft shield (controller ILI9486 )

[qbox4u]

Solution:
Add new generic setup file for Wemos D1 R32 in the folder User_Setups

Tested: OK

//***************************new setup file ******************************
//Setup for Wemos D1 R32 with 3.5inch TFT LCD shield

// https://nl.aliexpress.com/item/1005001928029759.html?
// This board is using the paralel interface !!!!
//
// The reason for not working is that the Wemos esp32 board connect CS,DC ands reset signals to
// a2 a3 and a4 , but these pins are only for "INPUT!!!! use
// You need to modify the Wemos D1 R32 board as follow:
// Boot issue:
// Add 330 Ohm resistor . .==> espressif/arduino-esp32#7562
// White screen issue:
// Connect gpio_15,33,32 to A1,2,3 .==>https://forum.arduino.cc/t/help-mcufriend-3-5-tft-lcd-480x320-esp32-solved/559854/5

There are lots of potential setups, so it is expected that an existing one is used as a template.

The addition of the 330 R resistor is an interesting idea, but will load the pin if used for other purposes. I have used a higher value resistor pulling down to 0V in the past, ISTR 10K was OK.
