unknown OID was met when running cmsparse about gmssl

[emmansun]

严格按《GB/T 35275-2017 信息安全技术 SM2密码算法加密签名消息语法规范》来讲，国密SignedData里的DigestAlgorithmIdentifiers的值只能是SM3的OID，也就是1.2.156.10197.1.401。有些实现兼容性好一点，就算这里放了SM2Sign-with-SM3，也就是1.2.156.10197.1.501的话，也能解析。

It is actually A correct Signature algorithm sm2-with-sm3, but gmssl cmsparse just failed to treat it.
I further run it on some other data, got similar error:

gmssl cmsparse -in cms-signed.pem

看起来本项目只支持国密CMS，也就是《GB/T 35275-2017 信息安全技术 SM2密码算法加密签名消息语法规范》中定义的OID，不支持国际标准。

[sunriseup]

gmssl should just parse and print it if it failed to recognize it.

gmssl should just parse and print it if it failed to recognize it.

这应该是项目定位问题，它不是一个通用的ASN.1数据Parse工具，无可厚非。

I deleted some codes ：
if (*info == NULL) { asn1_object_identifier_print(stderr, 0, 0, "Unknown OID", NULL, nodes, nodes_cnt); error_print(); return -1; }
built and run on the same pem file, got the following result
