22.08

What's new:

• Fixed the segmentation fault bug
• Added json format support, in addition to pos. Usage by -fmt or --format option: ./smashpp -r ref -t tar -fmt json and ./smashpp viz -o simil.svg ref.tar.json. The visualizer automatically detects format of the position file
• Added long options support for all options of Smash++ and the visualizer, e.g., ./smashpp --reference ref --target tar --level 1 --format json and ./smashpp -r ref -t tar -l 1 -fmt json are equivalent
• Added viz in addition to -viz for the visualizer. Usage: ./smashpp viz -o simil.svg ref.tar.pos
• New help page for Smash++ and the visualizer. Usage ./smashpp or ./smashpp viz
• New docker image: smortezah/smashpp:22.08, based on ubuntu:22.04
