**Do this after finalizing the serial communication protocol and building out the follower side of the application.
The leader will respond to gpio inputs (the chain pull, etc.). It needs to: • manage application state and notify followers of a change in application state • handle the decoding of video files for the LED matrix • play videos on its own screen • (low priority) update files on followers via UART serial when its own media folders have been changed (related issue)
