Specify the crossOrigin attribute when loading the module

[j-f1]

This allows scripts like React to properly listen to the error event, allowing better debugging.

This will break require against a domain that doesn’t have CORS enabled, however. This should probably be an option. Hmm.

That’s unfortunate :(

Here are a couple ways of making it an option:

require('d3', { cors: true })
require.cors('d3')

Note that while the first one doesn’t currently work, it has syntactic parallels with how require.alias supports custom module values (maybe require could support them in the future?), so I prefer the second one. The second one also would make the code much simpler.

I’ve added a test, but it seems yarn test doesn’t actually run the tests.
