fix(google-maps): Update Clusters when moving map

[ItsChaceD]

This PR addresses #1309, where (on android) clustering does not update when the map is moved, rotated, or zoomed in/out. It also allows modification of the minimum cluster size so behavior can be matched across all platforms.

types say 4 is the default for minClusterSize, but the default is only being set to 4 for web.
Is it 4 the default native value on Google Maps SDK? or should it be set to 4 there too if the minClusterSize option is not passed?

This should be two separate pull requests, one for the feat and another for the fix, or at least turn this into a feat PR.

Yes, you are right, they should be separate PRs. I split this into #1398 and #1399

And yes, 4 is the default native value for the Google Maps SDK on Android & iOS. I think this is different on web, so I explicitly set it to 4 if it is undefined.
