Add the possibility to import the tool as module

[moty66]

why not?

const ApacheStatus = require('apache-status');

let a  = new ApacheStatus([
    {url: 'http://example.com', client:'6.*'},
    {reverseDnsLookup: true, client:'host.*'}
]);

a.parse((res) => {
   if (res.length) {
       console.log(a.connections[0].CLIENT, a.connections[0].METHOD );
    }
}, (err) => console.error);

This add the possibility to build other node packages using this repository.

What do we need to do

Really little,

• the output option need to be optional in a first place, and ./src/apache-status.ts has to add it manually.
• Creating an index.js file in the root where we have to export the ApacheStatus class.
• Small rewrite of the class ApacheStatus to externalize the command line args parsing
