Exports the following items: - TimeStampReq() - TimeStampResp() Also adds TimeStampedData() support to asn1crypto.cms.ContentInfo(), TimeStampedData() and TSTInfo() support to asn1crypto.cms.EncapsulatedContentInfo() and some oids and value parsers to asn1crypto.cms.CMSAttribute(). Other type classes are defined that help compose the types listed above.
