Feature Request: Download/Upload project data in Generator.

[Kamesuta]

Ultimate Advancement Generator allows me to save project data to Google Drive, but I find it inconvenient that I cannot share it with others.

I would like to share project files via Git, Discord, etc., and develop advancements with multiple developer.

Therefore, I would like Generator to be able to export/import project data in JSON data, etc.

Great idea, I'll do it surely in the future!
