CI: Run tests on larger datasets

[namannimmo10]

This is an attempt to run the tests on larger datasets available on Zenodo https://zenodo.org/records/14338424

Todo:

• Make sure the data files are downloaded
• Add tests and make sure they pass on the CI

If you wish to run Zenodo tests as part of the CI workflow on a PR, please include the label run-zenodo-tests - then it will run all the tests. It's an extra optional step in the workflow:

      # Optional: Run Zenodo tests only if PR has a label
      - name: Download and run Zenodo tests
        if: contains(github.event.pull_request.labels.*.name, 'run-zenodo-tests')
        run: |
          chmod +x ./.scripts/download_zenodo.py
          ./.scripts/download_zenodo.py zenodo-tests/large_data_archive
          pytest zenodo-tests/
