Handy utility function to get output of shell command piping input to stdin (requires Python 3.5+).
>>> pipe('md5sum', 'This is a test')
--> 'ce114e4501d2f4e2dcea3e17b546f339 -\n'
>>> pipe('md5sum', b'This is a test')
--> b'ce114e4501d2f4e2dcea3e17b546f339 -\n'
>>> pipe(['gzip', '-c'], b'This is a test')
