Separate ZMQ from MessagePack, switch to pub/sub socket

Indexamajig uses only ZMQ, to receive streaming data, while libcrystfel
uses only msgpack to implement another type of image format.

The two of these are eventually tied together in process_image, which
does this:  if ( have_zmq_data ) interpret_zmq_data_as_msgpack;
 - however, they would be easy to split up if we wanted to do something
 else (CBF data over ZMQ, anyone?).

This commit also switches the ZMQ connector to use a pub/sub socket
instead of a request/reply one.  This matches changes in OnDA.

At the moment, the MessagePack image reader simply dumps the object to
disk.
