RSA-PSS signature params are parsed into a mess

[kpp]

Here is a x509 pem cert.txt signed with RSA_PSS_SHA384.

openssl x509 -text -in cert.txt -noout gives clear info of the signature algorithm:

        Signature Algorithm: rsassaPss         
         Hash Algorithm: sha384
         Mask Algorithm: mgf1 with sha384
          Salt Length: 0x30
         Trailer Field: 0xBC (default)

Unfortunately with your cratecertificate.signature_algorithm.parameters are parsed into a mess:

params = BerObject {
    header: BerObjectHeader {

Would you please fix it?
