LFU - Lazy Firmware Update

A script that allows you to conveniently update the firmware with orange pi on the electronic board of the 3D printer. It uses 2 pins on the Orange Pi, which are connected via 1 kΩ resistors to the NRST and BOOT0 signals on the printer's electronic board. This allows the script to automatically switch the device to DFU mode, help dfu-util update the FW, and then start the new FW.
