OfflineRegionManager (legacy) createOfflineRegion: download speed drop

Environment

• Android OS version: 11
• Devices affected: Samsung Tab Active Pro
• Maps SDK Version: 9.1.0, 10.16.0, v11.0.0-beta.4

Observed behavior and steps to reproduce

I noticed a significant speed drop in v10(v11) compared to v9. Here are several benchmarks for the same region

bounds: [
      [10.60776473348605, 59.874330907868426],
      [10.712617871809584, 59.92020667067757],
 ],
minZoom: 4,
maxZoom: 16,
styleURL: 'mapbox://styles/mapbox/light-v10'

v9: 6s 1039/1039 resources; 11759854 bytes downloaded
v10 legacy manager: 16s 1035/1035 resources; 11358923 bytes downloaded
v10 new tile manager: 20s 16/16 resources; 68958332 bytes downloaded

Note: The iOS legacy manager v10 has the same speed performance as v9 (iOS simulator), so the problem is only relative to Android. I tested with different tile servers (self-hosted and Mapbox) in different regions by using RN bridge and the latest Test Android app. The behavior is the same, region creation is slower almost 3 times for v10. Is it expected?

Expected behavior

Expected to have at least the same performance as in older versions.

Comienza con app/src/main/java/com/mapbox/maps/testapp/examples/LegacyOfflineActivity.kt y reproduce createOfflineRegion usando los bounds, los niveles de zoom y la style URL del issue en Android. Compara los recuentos de recursos, los bytes y el tiempo transcurrido con los resultados indicados para v9 y v10; se considerará terminado cuando la regresión de Android esté explicada y la creación de la región ya no muestre la ralentización indicada.
