### Your question

First of all, thank you for the great plugin!

I'm building a navigation app that needs low frequency (high `distanceFilter` and `intervalDuration`) location updates at the beginning but higher frequency (low `distanceFilter` and `intervalDuration`) as the user reaches the end of their journey.

IIUC iOS recommends adjusting the `desiredAccuracy` and `distancefilter` values to optimize for battery usage. It makes sense that this applies to Android as well.

Is there a way to update these values without cancelling and re-creating the Position stream?

Or is there a way to retain the Foreground service even when cancelling and re-creating the stream?
Because otherwise on Android re-creating fails with `android.app.ForegroundServiceStartNotAllowedException: Service.startForeground() not allowed due to mAllowStartForeground false`; as applications running in the background cannot create foreground services.

I'm happy to contribute a PR if this feature does not exist and you'd be willing to point me in the right direction.
