loadStructuredBinaryData<T> method

@override Future<T> loadStructuredBinaryData<T>(String key, FutureOr<T> parser(ByteData data))

Retrieve ByteData from the asset bundle, parse it with the given function, and return that function's result.

The result is not cached by the default implementation; the parser is run each time the resource is fetched. However, some subclasses may implement caching (notably, subclasses of CachingAssetBundle).
