- update to 2.13.1:
* Updated type definitions for mypy 1.0.0, removing a
dependency on implicit Optional types, and working around an
issue that could trigger a mypy internal error.
* Updated unit tests to avoid calculation of SHA-1 signatures,
which are no longer allowed in cryptography 39.0.0.
- drop remove-sha1.patch (upstream)
