Log Message:
py-asn1: updated to 0.5.1

Revision 0.5.1, released 20-11-2023

- Added support for PyPy 3.10 and Python 3.12
- Updated RTD configuration to include a dummy index.rst
  redirecting to contents.html, ensuring compatibility with
  third-party documentation and search indexes.
- Fixed the API breakage wih decoder.decode(substrateFun=...).

  A substrateFun passed to ``decoder.decode()`` can now be either
  v0.4 Non-Streaming or v0.5 Streaming. pyasn1 will detect and
  handle both cases transparently.

  A substrateFun passed to one of the new streaming decoders is
  still expected to be v0.5 Streaming only.
