 HoodLoader2 Run Bootloader example

 Starts Bootloader mode.
 This is useful if you only want to use
 the USB-Serial bridge again.
 
 You could delete the program with avrdude,
 but this sketch is way simpler to upload.
 
 It forces a watchdog reset,
 meaning the bootloader is started completely indipendant.
