(Un)original Prusa Heated Drybox - Port and Modification for Arduino Nano ESP32

This project is intended to be used with the (Un)original Prusa Heated Drybox but

• with an Arduino Nano ESP32
• a single rotary button encoder
  • short press outside of menu toggles LEDs
  • long press enters menu or confirms menu entries
  • short press in menu toggles menu pages
• three separate MOSFET for heater, fans, and LEDs
• three additional DS18B20 temperature sensors, one in the duct and two at the front of the drybox
• MQTT and Home Assistant autodiscovery
