Component Improvements

With MQTT transport protocol mapping, it is no longer necessary to specify whether UADP or JSON will be used as message mapping. QuickOPC will automatically recognize the message mapping, and is able to receive both UADP and JSON messages on the same connection. For more information, see OPC UA PubSub Automatic Message Mapping Recognition and OPC UA PubSub Transport Profiles.
The JSON message mapping now also accepts transport messages that are (incorrectly) formatted as an array of network messages, in order to better cope with buggy publishers.
Added OriginPattern property to the UASubscribeDataSetFilter class. It allows to specify a filtering pattern for the origin of the dataset message. The origin is e.g. a MAC address in the Ethernet transport, the IP address in the UDP transport, or the topic name in the MQTT transport.
Added MessageMappingName property to the UADataSetHeader class. Contains the name of the message mapping ("Json" or "Uadp"), if known.
The UAPublisherId and UADataSetHeader classes now implement the IComparable<> interface.

The table of dataset header counts, displayed at the end of uaSubscriber subscribeDataSet command execution, is now ordered by publisher Id, writer group dataset writer Id&name, dataset class Id, and origin.
Added --DistinctHeadersOnly|-dho option to the uaSubscriber subscribeDataSet command. The options changes the command output so that only dataset header information is displayed, and only when a dataset with a new, distinct header is received. With this option, you can easily collect information about "who is publishing" over a period of time.
