querySourceFeatures returns wrong type for 'cluster_id'

Environment

• Xcode version: 13.2.1
• iOS version: latest
• Devices affected: IPhone 12, IOS Similator
• Maps SDK Version: 10.2.0

Observed behavior and steps to reproduce

I use the querySourceFeatures call from mapbox SDK to get the cluster_id value that I need to highlight the cluster on the map. But there is an issue with type conversion value for cluster_id in MapboxCoreMaps. The querySourceFeatures function returns the wrong type when cluster_id=1 (in MapboxCoreMaps, this value is converted to boolean type instead of number, i.e. now I get cluster_id=true ).

I have attached a screenshot for more details:

Expected behavior

I'm expecting to get the value of cluster_id as a numeric value.

@alexeysatsunkevich thank you for reporting this issue. I am able to reproduce this on v10.2.0 with our SymbolClusteringExample and will investigate the root cause.
