Image url and size

[vonloxx]

Looking at code here:
https://github.com/front/g-section-row/blob/master/src/section-row/index.js#L242-L247
I think there's going to be issues:

• According to WP API reference (https://developer.wordpress.org/rest-api/reference/media/), there's no sizes property at media object anymore. It's located at media_details property. So it should get from media.media_details.sizes.large.source_url.
• Still, I think the block shouldn't get a specific size image. Should get the original and/or add a sidebar option to let the user choose. Not sure how it work in WP but in Drupal the image styles/sizes can be altered and, for example the large size option may not exist.
