Add support for UFW

Hello,

First of all, I would like to thank the creators / contributors of this lib, it is very useful for my projects !

I want know if it possible to add support for ufw command, like ufw status 😃

Thank’s

It’s okay for me, haven’t seen any bug, nice job ! I’ll use it to make an firewall rules editor on my app

Looking great, what’s the behavior if there’s a range for the port, like my screen, line 4

And what’s the behavior for apps ? If you use the following command : ufw allow openssh

In rules you can change number by index, because it’s the index for the rule, right ?

What’s the new_profiles field purpose ? Btw, I didn’t know if you can get the rules when UFW is disabled

– I think you can split for the subnet, because if I use this parser, I prefer to have all part of a field separately, same for logging_level.

PS: flat object is really good, I’ve done some deep object, but it’s not a really good way… PPS: If you can convert words like “Anywhere” to something more like “0.0.0.0” it could be nice too…
