add getBoundsReactFromPoints, change in findLocationById

Added:

• getBoundsReactFromPoints

Example:

function setViewBoundsByPoints(heremaps) {
    var topLeftPoint = { lng: 55.1021576, lat: 25.064732 };
    var bottomRightPoint = { lng: 54.1021576, lat: 24.064732 };
    
    var bounds = heremaps.getBoundsReactFromPoints(topLeftPoint, bottomRightPoint);
    
    heremaps.setViewBounds(bounds);
}

$scope.onMapready = function(heremaps) {
 setViewBoundsByPoints(heremaps);
}

Changed in API:

• findLocationById now returns json (PR: #14)
