Reviewed by Alex Christensen.

FileReaderLoader is limiting the size of data that can be read.
This restriction is not needed when reading data via a ReadableStream.
We stop allocating a buffer in FileReaderLoader for ReadType::ReadAsBinaryChunks as this is unnecessary.
Instead, we let the client store the buffers.

Manually tested for big files.
