I have tried to run the "data-update-2025" branch today and ran into some issues that this PR aims to improve. Here is a list of the changes I am proposing (that fixed every issue that I had):

• Update GBPT importer to support newer version of the database (from V3 on without sheet "Below Threshold").
• Correct GPD file name in config.yaml.

• Update path to powerplants.png in README.
• Fix typo in docstring of gather_fueltype_info() (cleaning.py) and MASTR() (data.py).

Yes, it's also a problem for the target branch. Nothing for you to worry about.
