After the change of AGSTiledMapServiceLayer, the cluster is abnormal.

When using "https://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer" service, the cluster function is normal, but when the "http://www.digitalcq.com/RemoteRest/services/CQMap_IMG/MapServer" service is used, there is always only one point in the cluster.I've been bothering me for a long time.

And, initialEnv changes to the following：
AGSSpatialReference *reference = [AGSSpatialReference spatialReferenceWithWKID:4490];
AGSEnvelope *initialEnv = [AGSEnvelope envelopeWithXmin:105.3831598117314
ymin:28.897172489811304
xmax:108.13817851680021
ymax:30.46728535770415
spatialReference:reference];
[self.mapView zoomToEnvelope:initialEnv animated:NO];

Yeah. The implementation assumes a Web Mercator tiling scheme. I am working on an update to Runtime 100.x (#22) and will see if I can make it more generic.

In the meantime, just tweaking the grid's cell size might get you better results (it's a completely broken and arbitrary calculation at the moment 😬). See:

	AGSUnits screenUnits = AGSUnitsInches;
	double cellSizeInMapUnits = AGSUnitsToUnits(cellSizeInInches, screenUnits, mapUnits);
