Add option to generate barcodes instead of QR Codes

[JOOT49]

It is much easier for our team to scan barcodes as we already have a barcode scanner that won't work for QR codes.
Adding the option to do this would make this the go-to scouting program for our team.

@JOOT49 - Have you used barcodes before? I was under the impression that barcodes couldn't encode very much information.

Bar codes specifically code39 can handle up to 43 alphanumeric characters.
