v1.8.1

• Fixed packaging and runtime errors caused by conflicts with an incompatible system Python installation or pip packages installed in the user's home directory. The embedded Python now always runs in isolated mode regardless of command line flags.
• Fixed packaging error on Windows when the Conan cache path contains spaces.
• Fixed Python include dirs being added twice (didn't cause any issues, just noise on the command line).
• Fixed openssl v3 mistakenly being enabled for Python 3.10. While 3.10 has preliminary support for openssl v3, Python 3.11 is the real minimum requirement for full support.
• Bumped default openssl to 1.1.1w for Python < 3.11 and v3.1.2 for Python >= 3.11.
