Allow PDF417 barcodes to reduce modules by shaving off padding.
The way it was working before is:
Look at the width and height provided for the barcode. If the maximum
number of codewords to fit in that space was within the spec limits
(1 <= cols <= 30 and 3 <= rows <= 90), cram as many codewords as
possible. The unused space was filled with padding.
With this CL, instead look at the amount of content that needs to fit
into the barcode and favor fewer codewords rather than as many as
possible.
