[FEATURE REQUEST] - getopts - parse cli arguments

[nyxnor]

Describe the solution you'd like

I want getopts to parse cli arguments. It will be cleaner.

Describe alternatives you've considered

• getopts - posix spec
• getoptions - awesome tool but not widely spreaded - downside is building from another project.
• stackoverflow example

Additional context

Have no time to do this right now, but it is a medium priority goal.

[nyxnor]

Imagine using default options and omitting them. as in HiddenServiceVersion, the only available v now it 3, so it can default to 3, but when v4 comes out, it will default to the greatest/more secure version and let both be options.
There are many more things that can be improved with getopts.

Implementiong bare hands because posix getopts is horrible for only short options and getoptions is out of my league.

available args:

--service ssh,xmpp
--service=ssh,xmpp
--service "ssh xmpp"
--service "ssh,xmpp"

So basically anything to fit any need.
