Add option for noInterop

[vikr01]

Similar to babel-plugin-transform-es2015-modules-commonjs, allows the user to specify an option for noInterop.

.babelrc

{
  "plugins": [
    ["dynamic-import-node", {"noInterop": true}]
  ]
}

In:

(async()=>{
  const foo = await import('foo');
})()

Out:

(async () => {
  const foo = await Promise.resolve().then(() => require('foo'));
})();

Thanks, this seems fine - but can you also add test cases for it?

I've added some test cases. Copied all of the expected.js files and removed the interopRequireWildcard.
