* Clamp the CoarseLocationUpdate packet at a maximum of 60 positions per packet. This is a limitation of LLUDP, nothing we can really do about it
* Marking CoarseLocationUpdate as *not* zerocoded. Zerocoding can only save space when a packet contains three or more contiguous zeroes, and will use more space if it contains single zeroes randomly scattered through the packet (which is what you see when you send a long list of UUIDs)
