ALLOWED_EAN_EXTENSIONS Enum
Allowed extension lengths for EAN or UPC barcodes. Other formats will ignore this. Maps to an of the allowed extension lengths, for example [2], [5], or [2, 5]. If it is optional to have an extension, do not set this hint. If this is set, and a UPC or EAN barcode is found but an extension is not, then no result will be returned at all.
