Add a #getBytes() method to DeterministicWriter that returns a ByteString. By default it just delegates to the existing #writeOutputFile, but implementations may choose to override if they have easy access to a ByteString.

Also change some DeterministicWriter implementations that do have easy access to the ByteString.
