- Add ss parser
- Add stat parser
- Add /etc/hosts parser
- Add systemctl parser
- Add systemctl parser (includes list-jobs, list-sockets, and list-unit-files)
- Add -r and raw=True options. By default, jc will now convert numbers and boolean, if possible, and add other semantic information, while the raw output will keep all values as text and provide a more literal JSON output
- Add -q and quiet=True options to suppress warnings to stderr
- Add -d option to debug parsing issues
