* deprecate snapshot_override, which is an obsolete predecessor of hot reload * give the APKAssetProvider to the engine in the initial call to RunBundle * later calls to Engine::RunBundleAndSource or Engine::SetAssetBundlePath will replace the APK asset provider with a DirectoryAssetBundle that uses the newly pushed assets
