Compatibility with Xamarin.Forms.GoogleMaps.Clustering is broken

[raver99]

VERSIONS

• Xamarin.Forms.GoogleMaps - 5.0.0
• Xamarin.Forms - 5.x.x

PLATFORMS

• Android
• iOS
• [? ] UWP

ACTUAL BEHAVIOR

As of version 5.0.0 you cannot use the plugin for clustering because the plugin library does not have access to internals of this library, due to the fact that "InternalsVisibleTo" attributes where removed.

Please add back the attributes to support clustering again. See Commit
