We will need some way to decode arbitrary data via IMFTransform objects, 
but it seems preferable to avoid having to implement more objects than 
we need. E.g. trying to catch as many as possible via a generic decoder 
seems like a good idea. In that case we'd want to use MFTEnum() in 
FAudio instead of hardcoding the CLSID.
