Create a pipeline to perform the unbundle operation on infile input.
The resulting unbundled image will be written to 'outfile'.
:param outfile: file obj to write unbundled image to
:param enc_key: the encryption key used to bundle the image
:param enc_iv: the encyrption initialization vector used in the bundle
:returns multiprocess pipe to read sha1 digest of written image

Synchronously copy data from infile to outfile, updating a progress bar
with the total number of bytes copied along the way if one was provided,
and return the number of bytes copied.
This method must be run on the main thread.

Read data from infile and write it to outfile, calculating a running SHA1
digest along the way. When infile hits end-of-file, send the digest in
hex form to result_mpconn and exit.
:param infile: file obj providing input for digest
:param outfile: file obj destination for writing output
:param digest_out_pipe_w: fileobj to write digest to
