Verify that all CRW fasta files match the PS files

[AntonPetrov]

In one case, d.5.e.D.melanogaster.2.bpseq, the sequence was slightly different between the file in crw-fasta-no-pseudoknots and the corresponding postscript file. There may be other cases like this that prevent Traveler from drawing the 2Ds, so we need to verify that all fasta files match the ps files.
