    [BEAM-814] Dataflow: parallelize hashing/compressing of files to stage

    R: @lukecwik 
    
    This is a WIP for the linked issue. Early feedback appreciated.
    
    Decided to parallelize just hashing/compressing separately from uploading, because this should use a very tiny buffer per file and so can be parallelized nearly arbitrarily. In contrast, uploading uses a very large buffer and cannot be parallelized simply.
