Test if multiple barcodes might have been single barcode with multiple reads

[claybarrett]

When multiple barcodes are detected, sometimes there's actually just one, and one result is a partial read, like this result:

[{'type': 'CODE39', 'data': '2660'}, {'type': 'CODE39', 'data': '102660'}]

Maybe a simple regex to check if one result is completely contained within another would allow a smarter choice for these (after a test if they are not of the same length, same length results would not be "nested reads"). Otherwise we had discussed some sort of config file option to test the read barcode format against.
