CLI args shouldn't be parsed when importing package

Description

args.argv should only be invoked when require.main === module is true, otherwise a simple require to this module will parse command line arguments unexpectedly. This is specially harmful when you are importing this package at the top of your module and trying to create your own set of command line options.

Reproduction

Create a node.js file importing this package: my_test.js

const Auth0 = require('auth0-deploy-cli');

console.log('CLI arguments: ' + process.argv);

Invoke this file using node: node my_test.js --help

That shouldn’t show auth0-deploy-cli help.

To whom it may concern, I’ve worked around this issue by removing arguments from process.argv before requiring auth0-deploy-cli.
