add firmware update via FOAT example

  - Firmware update Over AT (FOAT): Allows upgrading of the module firmware via binary 'delta' files over the AT interface using AT commands.
  - Firmware update Over The Air (uFOTA): Allows upgrading the module firmware via binary 'delta' files over the air interface based on u-blox client/server solution (uFOTA), using Lightweight M2M (LWM2M). This requires the customer creats a campaign with u-blox to identify IMEI's of modems and access to the u-blox uFOTA server

 You can use the {{{ATI}}} command on the AT tty to determine the firmware version (see [#at AT commands below])
+
+Examples:
+ * FOAT:
+{{{#!bash
+apt install lrzsz # X/Y/Zmodem
+DEVICE=/dev/$(for i in $(ls -d /sys/bus/usb/drivers/option/*/ttyUSB*); do basename $i; done | tail -n1)
+echo "DEVICE=$DEVICE"
+stty -F $DEVICE cs8 -parenb -cstopb -ixon
+echo -n -e "AT+UFWUPD=3\r" > $DEVICE
+sx -kv firmware.bin <$DEVICE >$DEVICE
+sleep 1
+echo -n -e "AT+UFWINSTALL\r" > $DEVICE
+}}}
+  - the actual installation of the firmware takes place when the modem receives the {{{AT+UFWINSTALL}}} command and can take up to 5 minutes to complete. If the binary delta can not apply to your firmware (ie you have a delta for the wrong version) it will fail and your firmware will go un-updated
+  - the update is fault tolerant... in case of power outage etc the modem will boot with the old firmware
