Simple function to calculate a new point's latitude and longitude based on provided start point, bearing and distance.

	fun getPointByDistanceAndBearing(lat: Double, lon: Double, bearing: Double, distanceKm: Double): Pair<Double, Double> {
	val earthRadius = 6378.1

	val bearingR = Math.toRadians(bearing)

	val latR = Math.toRadians(lat)
	val lonR = Math.toRadians(lon)

	val distanceToRadius = distanceKm / earthRadius
