v1.2.1 Bugfix release for Windows (Python library in userspace)

v1.2.1 (2022-11-13) - Fixed Python libraries (pyzmq) not findable when installed in userspace

• On Windows, pip installed libraries might be installed outside the Blender dir.
  When failing to import a library, an extra import attempt adds site.getusersitepackages() to sys.path.
  • Blender on Windows might be installed under: C:\Program Files\Blender Foundation\Blender 3.3\3.3\python\bin\python.EXE.
    However, even when referring to this binary, libraries might still be installed under e.g.
    C:\users\{user}\appdata\roaming\python\python310\site-packages
