Savable settings

This release adds the ability to save settings which are applied at boot.

Save settings

You can save the colour, effect and brightness to the device so that it will start up with those options.

./example.sh <DEVICE-SERIAL-NUMBER> <COLOUR> <EFFECT> <BRIGHTNESS> --save

eg

./example.sh DE64A876CF551522 red pulse 10 --save

If you save your settings you should see the LED flash white 4 times and then return to your saved settings. On boot if you have no saved settings the LED with flash blue once, then red. If you have saved settings the LED will flash blue once and then green twice before applying those settings.
