"examples/LCD_PCF8574/PCF8574/PCF8574.ino" is broken on Arduino MEGA 2560 R3

[realRobotix]

Hardware:

• Arduino MEGA 2560 R3
• 20x4 I2C LCD
• quad encoder (encA: 2, encB: 3, encBtn: 22)

1. Problem: neu-rah/PCINT doesn't compile Fix: https://forum.arduino.cc/t/help-understanding-and-fixing-int-mode-type-has-not-been-declared/1080621

2. Problem: Rotating the encoder still doesn't work, but pressing it does. Tried to do some simple debugging, but I have no idea how c++ works.
