[erlang-questions] Update to public_key in anticipation of CRL support

[Drew Varner]

It looks like CRL support will enter Erlang in the future [1]. CRLs sometimes use the signature algorithm ID 1.3.14.3.2.29 for SHA instead of 1.2.840.113549.1.1.5 [2][3]. Can we update pubkey_cert.erl to understand this OID [4], even though CRL functionality isn't in place yet? It might be useful in other situations also.

Thanks,
Drew
