Need object when reading/writing encrypted PDFs (to decrypt/encrypt strings),
RC4 writing is now working, AES-128 needs work, AES-256 hasn't been done yet.

More efficiently implement reading of integers vs. indirect references.
"testpdfio filename.pdf objnum" now shows object value if there is no stream.

Clean up debugging printfs.

Switch to using double for numbers, since they are also used to record lengths
and other potentially large contents.

for newer Acrobat so we'll need to implement those, too.
