Rotary Display Menu

This is a simple menu program for use with small OLED displays such as the SSD1306. It is designed to be used with a rotary encoder and a push button.

The menu is displayed on the OLED and the user can navigate through the menu using the rotary encoder. The push button is used to select an item in the menu.

The app will show all the micropython files on the device and allow the user to select one to run.
