Overlapping Feature Spiderfier is not working on Clustering

[harshithpawar94]

I am implementing a spiderfier of markers in our web application.
if I use map data object it works fine, but the issue is when I use the dataLayerClusterer object on OverlappingFeatureSpiderfier instance.
for example:
dataLayerClusterer = new DataLayerClusterer({
"map": map,
"maxZoom": 19
});
featureSpiderfier = new OverlappingFeatureSpiderfier(dataLayerClusterer);

Error:
I am getting this error in browser console:
Uncaught: Layer map should be set before instantiating OverlappingFeatureSpiderfy!

Sorry, the library is designed to work directly with a data layer. I expect it would need a lot of changes to work with the clusterer - I'd happily take a PR though if you want to take it on.
