Update BS PNP to create guides and outer cropmarks

These are now needed as Button Shy has changed their PNPs to a different
standard, most notably the cards are now smaller by 1mm in each
dimension.

Rather than use the new PNPs directly, extract the card images (using
`pdfimages -all`) and arrange them on these guides and inner/outer
cropmarks which the old format. This allows our PNPs to be of the same
dimensions as previous ones.
