Title: Remove caching of stream data and fix object loader for streams.

Should help with memory usage. Since I removed `e = e.makeSubStream(0, e.bufferLength, e.dict);` I had to change the object loader to check the base streams for missing data since it was no longer trying to fetch it all when the object was requested.
