Description
Android SDK causes a crash whenever [queryRenderedFeatures] is called and the data is corrupted.
Corruption ticket created in mapbox android repository -> https://github.com/mapbox/mapbox-maps-android/issues/2619
### Reason
GSON cannot jsonify Infinity and NAN floating numbers. Which results in the following line crashing:
```kotlin
fun com.mapbox.maps.QueriedFeature.toFLTQueriedFeature(): QueriedFeature {
return QueriedFeature(JSONObject(this.feature.toJson()).toMap(), source, sourceLayer, state.toJson())
}
```

Research direction
Start at the toFLTQueriedFeature conversion shown in the issue and trace how queryRenderedFeatures reaches it. Read the linked Android corruption ticket for the affected data case, then reproduce the crash with corrupted data. Done means queryRenderedFeatures no longer crashes when Infinity or NaN values are present.
