I12BP8 955cb86fc1 Fix barcode checksum to include prefix letter ...

Pricer barcodes validate with (sum of all 17 chars) mod 10 == 0,
with the letter prefix contributing by its ASCII offset from '0'.
The old formula compared sum of the first 16 digits to the 17th,
rejecting valid codes like A4120365539013704.
