Fixed 1 bug (due to archive.org update) and added 3 functions (one from the to-do section)

fixed one bug:
fix InvalidURL (No host supplied) error due to updated json response on archive.org

added three functions:
added script that stitches the jpgs to a pdf file
added Exception so when the page download fails, it retries twice
added option to add config.py file with email and password

I just tried this out, and it's great that you fixed the InvalidURL issue, but it will crash trying to import the config module if one doesn't exist. I assume that was intended to be optional.

And I'm getting this error on the stitcher script with macOS 13.4.1:

Enter the directory of the images: chiltonstoyotace0000unse_b0s4
Enter the id of the book: chiltonstoyotace0000unse_b0s4
Traceback (most recent call last):
  File "~/git/archiveripper/stitcher.py", line 32, in <module>

OSError: [Errno 24] Too many open files: 'chiltonstoyotace0000unse_b0s4/253.jpg'

There is a pretty simple workaround, which is passing in a higher value to ulimit -n, but it might be a good idea to give a user-friendly message when this happens.
