Manage process.env.DEBUG to match namespace

[loic-moriame]

The management of process.env.DEBUG without searching to match a namespace isn't ideal when you develop a CLI with module debug

Indeed, when I try to debug my CLI a have a lot of message from ssllabs that I didn't want at this moment:

Line 220 :

process.env.DEBUG && console.log(`ASSESSMENTS: ${api.info.currentAssessments}/${api.info.maxAssessments}`);

Line 272 :

process.env.DEBUG && console.log(httpOptions);

Line 293 :

process.env.DEBUG && console.log(data);

I will try to make a PR to implement debug module if you are agree with it

I can see what you are saying. A pull request would be appreciated.

Are you OK if a add debug as dependency to handle this?
