[shawn111]

I'm submitting a

• bug fix
• feature
• documentation addition

What is the current behaviour?

As https://github.com/TeXitoi/structopt mention clap already support derive and structopt would not add new features.

What is the motivation / use case for changing the behavior?

Switch to clap, clean some dependency.

It looks good to me. I would like for @icepuma or @rawkode to also approve this before we pull it in in case they have some issue with replacing paw and structopt.
