jc changelog
20191117 v1.5.1
- Add ss parser
- Add stat parser
- Add /etc/hosts parser
- Add /etc/fstab parser

- Add -q and quiet=True options to suppress warnings to stderr
- Add -d option to debug parsing issues
- Add compatibility warnings to stderr
- Add documentation
- Updated iptables parser to allow --line-numbers option
- Updated lsblk parser to allow parsing of added columns
- Updated mount parser: changed 'access' field name to 'options'
- Updated netstat parser to allow parsing of unix sockets and raw network connections
- Updated w parser to fix unaligned data where blanks are possible
- Clean up code and reorganize package
20191031 v1.1.1
