xbee-init: script updated to use libgpiod tools 

Additionally:
   - The handling of gpios has been swapped so 'Set low XBEE_SLEEP_RQ' is done
 before 'Power cycle XBEE_RESET_N' to assure the device doesn't enter sleep mode.
   - Removed ExecStop entry from systemd service since it's doing nothing.
