Add multi-line imports

[jerrysu]

This adds support for multi-line imports wrapped in parentheses: #41

I added a test for:

@value (
  blue,
  red
) from './colors.css';

The following are also allowed:

@value (blue, red) from './colors.css';

@value (blue) from './colors.css';

Let me know if you'd prefer to change anything or would like to add or re-organize the tests somehow. I can also add to the README.md as well.

Any reason why this PR has not yet been approved? This is indeed very helpful if you import a lot of values from another file :)

would love to see this approved ASAP. Multi-line imports is a must for serious theming :-/

@ai Is there anything we could do to get the repo owner's attention? It's the css modules core plugins. They should definitely be maintained by someone... :-/

@andywer perhaps make an own fork - the remedy of last resort?

[andywer]

@witwit As a last resort, sure. But I would rather not if there is a way around... Maybe set some random deadline just for ourselves? Like two weeks and if there is still no solution at the time then we fork.

[witwit]

@andywer, sounds like a plan :-)

Any progress on this?

[geelen]

Sorry! This has been not-really-maintained for a while now. But I'm back.

Great! Thank you
