Make miyoo flip led blink when is under 5 percent battery

[Ampaex]

This commit will make the miyoo flip emit a battery warning making the status led blink when the battery is under 5% of capacity.
I attach a demo video where you can see that also works in-game:

This is actually similar to a feature I'll be working on the next major release. We're also going to make a new central hub for battery information for all devices that everything will go through. But, something like this might tie into something I had in mind, but for all devices.
