pari soname bump

Pari 2.13.0 is out, and comes with an soname bump. I have successfully rebuilt all consumers except sagemath in mock (the sagemath build is running now; it takes awhile), so I don't expect any problems. Once the sagemath build completes, I will put the various consuming packages through their paces to see if any problems arise. If not, I will do all the necessary builds in Rawhide next week. If no problems show up in Rawhide, I will consider updating Fedora 33 as well. Packages to be rebuilt: clisp eclib giac L-function python-cypari2 (requires an update to version 2.1.2b1) python-cysignals sagemath (will be updated to version 9.2) -- Jerry James http://www.jamezone.org/
