- fix acquire fail in tests (adcreg test)
- roi tests fail after overlapping invalid test and acquire after
- print udp dest mac in server properly
- fixed udp dst list get (server was not sending entry proper size to match proper struct size in client)
- updated server binaries and updated hard links in serverBin
- added documentation regarding gui:  zmqport and zmqip in terms of gui, rx_zmqstream
- removed print - probably ended there for debuggung

+    ``zmqport`` and ``zmqip`` need to be set up in shared memory before starting up the Gui. If the Gui is already running, change it in the Advanced Tab directly in the Gui.
+    
+    ``rx_zmqstream`` is set to 1 when the GUI is started, but has to be manually set back to 0 to disable zmq streaming in the receiver for better performance when not using the Gui.
+    
+    The GUI hwm (high water mark, which is like a measurement of the number of enqueued zmq packets) values are set to a low number (from library default of possibly 1000 to 2) to reduce the zmq buffer to display only some of the images. Resetting it back to -1 or 1000 should only matter if one plans to not use the Gui and still zmq stream without wanting to drop zmq images (eg. for external processing chain).
