Option media: color controls images

White has no "media metaobject"

Blue and navy share the same media metaobject. 

Brown has a video. 

Blue and white have no "variant image" set. The other variants have a folded shirt as their variant image. 

The variant images should be wiped out by the media set. They are only used by the product card. 

Each metaobject contains a reference to a color and a list of photos. If a selected option matches a color option defined in product.metafields.option_media[i].option then the media shoud be replaced with the list of media at product.metafields.option_media[i].media
