Support for hints, introduced in #31, contains some ambiguity in
UPC-AandEAN-13formats, which are very similar (visually they look similar, and both have 13 digits).There is no
.upcasymbiology in Apple Vision, so there is no way to distinguish if a scanned barcode is of formatUPC-AorEAN-13. What this PR does is check the provided hint, if a barcode of symbiology.ean13was scanned, if the hint used was.ean13or.upca, then that hint is returned as format.
