Failed to enable the Mitsuba Blender Add-on

Bug Description
I use pip to install the Mitsuba and specify version 3.0.1

When I enable the Mitsuba Blender Add-on, the report shows that AttributeError: module 'mitsuba' has no attribute 'set_variant'

And when I import mitsuba and call the same code in cmd and, it works well

To Reproduce
Steps to reproduce the behavior:

1. Download the latest release from the release section.
2. In Blender, go to Edit -> Preferences -> Add-ons -> Install.
3. Select the downloaded ZIP archive.
4. Find the add-on using the search bar and enable it.

Expected behavior

Hello,

Mitsuba needs to be installed in Blender's python environment (blender/3.3/python/bin/python.exe). Can you try installing Mitsuba there (python -m pip install mitsuba==3.0.1 --force-reinstall) ?

In any case, I would suggest waiting for #44 to be merged as it fixes some problems due to dependency installation versions.

Cheers!
