Extend by adding pdfioGetModDate and extend the pdfioinfo example
...
When exploring a PDF, it may be convenient to have the typical
informations delivered by some "Document Properties"---and some more
about the MediaBox(es).
So just add the function to get the ModDate and extend the
pdfioinfo example as an example of what the library do have
and pdfioinfo as a debugging tool also.

a significant improvement in open speed - from 2371 seconds (about 39.5 minutes)
to 3.1 seconds for one large test file (an ESRI standard).
