Version 2.0.0

• Major overhaul of the output subsystem. The new architecture is modular, multithreaded and can easily be extended with new output drivers. It also allows using multiple outputs simultaneously.
• New output configuration scheme. --output-file --daily, --hourly and --output-acars-pp options have been removed. All outputs are now configured using --output option. Adjusting command line parameters is therefore required to run the program. Run dumpvdl2 --output help for instructions or see "Output configuration" section in README.md for details and examples.
• Support for streaming messages over network using UDP/IP.
• Support for streaming messages over network using ZeroMQ publisher sockets. Requires libzmq library.
• Support for storing AVLC frames as raw data (without decoding) in binary files for archiving purposes. File contents can then be decoded anytime later, as if the frames were just received from the air. Requires protobuf-c library.
• Minor bugfixes.
