Bug description

switch_focus() and set_focusedLine() functions do not work on ESP32 platform, though the code compiles fine without any issue.

`#include <Wire.h>
#include <LiquidCrystal_I2C.h>
#include <LiquidMenu.h>
#include <Button.h>

// The I2C LCD object
LiquidCrystal_I2C lcd(0x27, 16, 2);

// Button objects instantiation
const bool pullup = true;
Button left(17);
Button right(16);
Button up(19);
Button down(18);
Button enter(23);

bool focus = false;

LiquidLine welcome_line1(1, 0, "LiquidMenu Q", LIQUIDMENU_VERSION);
LiquidLine welcome_line2(1, 1, "Hello Menu I2C");
LiquidScreen welcome_screen(welcome_line1, welcome_line2);

LiquidLine analogReading_line(1, 0, "Analog: ", analogReading);
LiquidLine DigitalReading_line(1, 1, "Digital: ");
LiquidScreen secondary_screen(analogReading_line, DigitalReading_line);
LiquidMenu menu(lcd);

void setup() {
Serial.begin(115200);

pinMode(analogPin, INPUT);

left.begin();
right.begin();
up.begin();
down.begin();
enter.begin();

lcd.init();
lcd.backlight();

welcome_screen.set_focusPosition(Position::LEFT);
secondary_screen.set_focusPosition(Position::LEFT);
menu.init();

menu.add_screen(welcome_screen);
menu.add_screen(secondary_screen);

menu.update();
Serial.println(menu.get_focusedLine());
}

void loop()
{
if (enter.released()) {
Serial.println("ENTER button pressed");
focus = !focus;
menu.switch_focus(focus);
Serial.print("focus line: "); Serial.println(menu.get_focusedLine());
Serial.print("focus: ");Serial.println(focus);
}
if (left.released()) {
Serial.println("LEFT button pressed");
menu.previous_screen();
}
}
