Enable South African Driving License parser

The South African Driver's License (SA-DL) defines the standard for driver’s license barcode data across South Africa.

To enable it, look at the example below;

                // Enable PDF417 symbology and South African Driving License parser
Barkoder.setBarcodeTypeEnabled(BarcodeType.pdf417, true);
Barkoder.setFormattingType(FormattingType.sadl);
    
// Beta: Parsers for data in South African IDs and South African Vehicle License Discs
Barkoder.setCustomOption("SADL_decode_ID", 1);
Barkoder.setCustomOption("SADL_decode_vehicle_disk", 1);

// Get SADL image - called when Barkoder returns a scan result (result is BarkoderResult)
const sadlImage = result.decoderResults?.[0]?.sadlImageAsBase64;
