[aur-requests] [PRQ#12277] Orphan Request for python-isbntools

[notify at aur.archlinux.org]

caleb [1] filed a orphan request for python-isbntools [2]:

Like [isbnlib](https://aur.archlinux.org/packages/python-isbnlib) this
has been flagged out of date for 5 months. I've adopted and updated
the lib, I can do the tools too.
