BytesLoader class abstract

An interface that can be implemented to support decoding vector graphic binary assets from different byte sources.

A bytes loader class should not be constructed directly in a build method, if this is done the corresponding VectorGraphic widget may repeatedly reload the bytes.

Implementations must overide toString for debug reporting.
