String and Subtype issues

[Kereemgd]

The addon currently exports gamma_socket.subtype as an empty string ("") instead of "NONE". Additionally, there's a string handling issue with the frame.label properties. By exporting and printing the material to another Blender file, you can recreate and diagnose these errors.

Github does not allow directly uploading ".blend" files.

Big thanks for this great addon.

Thanks for spotting these!

The gamma socket one seems like a bug with Blender. The subtype property is set to '' rather than NONE for some reason. I've submitted a bug report to Blender on the issue. Regardless, NodeToPython will just assume it's NONE and ignore it with v3.2.1, which is now in main

Fix for the bug report with this PR, looks like it's targeting the next Blender 4.2 LTS release
