Feature request: Add UPC +2 and +5 barcode extension scanning to ML Kit

[ethanwa]

+2 is used on magazines to denote issue number and on older comic books.
+5 is used on comic books to denote printing, variant, and issue number. It's used on books to denote retail price.

Both are often used in other capacities as well, but I won't research to list them all.

I would love to see Google add native support for these barcode extensions. Apple's built-in vision barcode scanner doesn't have either of these, and it would give me a reason to move to Google's ML implementation on both Android and iOS for my apps.

Thanks for the feature request. We'll discuss this internally and come up with a plan, so please stay tuned.

Is there any update on this feature? We'd benefit from this, too. We're currently using zxing, but would love to move to something more actively supported. However, the lack of the UPC extensions is the only thing preventing us from doing so.
