Retina @2x

Hi, It would be possible in future add option for creation additional @2x image size?
We have retina display, where it can be handy for example on homepage slider.

So plugin generate both size, original crop and @2x size.

$image = get_field( 'image');
$crop = image['url'];
$crop_retina = image['url_retina'];

Thank you for your work!
