Consider Default RouteDeviation/Snapping for various platforms and activities.

We'd like to provide some sensible defaults to make setting up ferrostar easier for a specific platform and navigation activity.

This would replace things like this ` RouteDeviationTracking.StaticThreshold(15U, 50.0),` in the Android demo.

Start by locating the Android demo code containing RouteDeviationTracking.StaticThreshold(15U, 50.0) and read how platform and navigation activity settings are assembled. Define the supported platforms and activities and the expected defaults before changing setup behavior; done means the intended cases use sensible defaults without that explicit configuration.
