Export a babel macro?

Hi @smrq thanks again for this plugin!

For storybook users using setups like create-react-app, using a babel plugin may not be an option; however a babel macro is. (This may only apply to CRA but it's a lot of folks I guess).

Would you consider adding a babel macro? I've done a POC here: https://github.com/tmeasday/require-context.macro/blob/master/require-context.macro.js

The basic idea is, you use it like:

import requireContext from './require-context.macro';

const req = requireContext('../stories', true, /.stories.js$/);

function loadStories() {
  req.keys().forEach(filename => req(filename));
}

loadStories();

When babel is run via storybook (i.e. NODE_ENV !== 'test'), it will output:

const req = require.context('../stories', true, /.stories.js$/);

function loadStories() {
  req.keys().forEach(filename => req(filename));
}

loadStories();

When babel is run via jest (i.e. `NODE_ENV === 'test'), it will output:

const req = __requireContext(__dirname, '../stories', true, /.stories.js$/);

function loadStories() {
  req.keys().forEach(filename => req(filename));
}

loadStories();

Does this make sense to you? I can submit a PR? (I'm not really sure what I am doing with babel though)

I ended up publishing a macro here.

https://github.com/storybooks/require-context.macro

I saw that there's been a PR open for a few weeks and figured you were busy.

Let me know if you'll accept a PR that essentially brings in the above library! I'd rather have the macro exported here, since it's basically all your work.
