Clustering should support diff util

[MikolajKakol]

Is your feature request related to a problem? Please describe.
My map has millions of points so I cannot add all of them at once. Hence what map moves I download items only visible on screen. When user does only small map movements points and clusters flicker and animations looks bad. This is because current implementation look like this:

    LaunchedEffect(itemsState) {
        snapshotFlow { itemsState.value.toList() }
            .collect { items ->
                clusterManager.clearItems()
                clusterManager.addItems(items)
                clusterManager.cluster()
            }
    }

So when ever items are updated clustering is recreated.

Describe the solution you'd like
I think we should be able to provide some diffing to only add or remove a subset of items.

Describe alternatives you've considered
I also though about just coping whole Clustering method and add custom logic, but it's not possible to reuse ResetMapListeners method.

Hi @MikolajKakol ,

Did you check the sample using the NonHierarchicalViewBasedAlgorithm? This only renders the screen content.

Hi @kikoso, it would be possible solution if I could populate map with all points from backend, but it is not possible to fetch all of them.
