libtasn1: Update to 4.16.0

* Noteworthy changes in release 4.16.0 (released 2020-02-01) [stable]
- asn1_decode_simple_ber: added support for constructed definite
  octet strings. This allows this function decode the whole set of
  BER encodings for OCTET STRINGs.
- asn1_get_object_id_der: enhance the range of decoded OIDs (#25).
  This also makes OID encoding and decoding more strict on invalid
  input. This may break gnutls' test suite before 3.6.12 as it was
  relying on decoding some invalid OIDs.
- asn1_object_id_der: New function

* Noteworthy changes in release 4.15.0 (released 2019-11-21) [stable]
- The generated tree no longer contains ASN.1 built-in types even
  if they are explicitly defined in the description. Previously
  a warning was printed when these types were seen, now they are
  ignored.
- Several fixes in ASN.1 definition parser, preventing several
  crashes and leaks in the tools due to improper ASN.1.
- Switched to semantic versioning.
