This takes a binary file for reading a pickle data stream.

        The protocol version of the pickle is detected automatically, so
        no proto argument is needed.

        The argument *file* must have two methods, a read() method that
        takes an integer argument, and a readline() method that requires
        no arguments.  Both methods should return bytes.  Thus *file*
        can be a binary file object opened for reading, an io.BytesIO
        object, or any other custom object that meets this interface.

        The file-like object must have two methods, a read() method
        that takes an integer argument, and a readline() method that
        requires no arguments.  Both methods should return bytes.
        Thus file-like object can be a binary file object opened for
        reading, a BytesIO object, or any other custom object that
        meets this interface.

        If *buffers* is not None, it should be an iterable of buffer-enabled
        objects that is consumed each time the pickle stream references
        an out-of-band buffer view.  Such buffers have been given in order
        to the *buffer_callback* of a Pickler object.

        If *buffers* is None (the default), then the buffers are taken
        from the pickle stream, assuming they are serialized there.
        It is an error for *buffers* to be None if the pickle stream
        was produced with a non-None *buffer_callback*.

        Other optional arguments are *fix_imports*, *encoding* and
        *errors*, which are used to control compatibility support for
        pickle stream generated by Python 2.  If *fix_imports* is True,
        pickle will try to map the old Python 2 names to the new names
        used in Python 3.  The *encoding* and *errors* tell pickle how
        to decode 8-bit string instances pickled by Python 2; these
        default to 'ASCII' and 'strict', respectively. *encoding* can be
        'bytes' to read these 8-bit string instances as bytes objects.
