Fix parsing certs with very large serial numbers
Certificates with large serial numbers (such as those from commercial vendors) previously failed to parse due to absent logic in the FakeOpenSSLCertificate parser. This would cause the module to abort and break any other roles depending on the cert expiry checking results. * Identifies large serials in HEX format for decimal conversion * Update unit tests to parse a large serial
