Verify an IPA's Signing Certificate

Example :

python ipa_cert_checker.py /Users/janedoe/Documents/Foobar.ipa /Users/janedoe/Documents/barfoo.cer

If any matching certs are found, the script will print something similar to:

Certificate (1) beginning: XCVBNM... matches the specified certificate: /Users/janedoe/Documents/barfoo.cer
