I'm using your work for professional purposes but I was faced to several issues and features needs. Therefore, I've taken the liberty to fork your project to fix issues and add some improvements. It would be a shame not to take advantage of this to benefit the initial project.

Here are my improvements :

1. Reformat the script file with default Ruff linting rules
2. Remove useless imports
3. Fix wrong MITRE database (originally link to Github URL page and not raw JSON file
4. Add .env file to configure script instead of editing it
5. Add external_id (ex: T1xxx for Techniques id) and depreciated property on nodes if available

Feel free to ask me for more information or any suggestions you would have before merging it.
