Geolocation Accuracy improvements

[Jaspur]

Description of the problem:
The accuracy of the Geolocation that is provided with the WatchPosition can be done better for iOS and Android.

Affected platform

• [ x ] Android
• [ x ] iOS

OS of the development machine

• [ x ] macOS

Other information:
For Android you better can use the "Fused Location" (#379)

And for Swift it uses by default:

self.locationManager.desiredAccuracy = kCLLocationAccuracyBest

But Best Accuracy isn't really the best option.
There are also the options kCLLocationAccuracyNearestTenMeters and kCLLocationAccuracyBestForNavigation See: https://developer.apple.com/documentation/corelocation/cllocationaccuracy

How can I chose myself which CLLocationAccuracy option to use?
