Sensor fusion + Speedometer app

[ldab]

1. Implement sensor fusion based on https://github.com/xioTechnologies/Fusion
2. A crude speedometer app (haven't really tested on motion) it is cold outside :cold_face:
3. few todo's but I think we can keep going?

PS. I wanted to keep the screen on, but It does not work, do you know why?

@ldab the screen is handled by zsw_power_manager. We don´t have an option to keep the display on yet.

We do, I have added an option in settings for it, but somehow it's broken now.

Edit: You need to restart for it to take effect.

PS. I think the new flick out need to check for this setting
