[1.0.0] Breaks with Django >=6.1 (seemed fine until Django <=6.0.8)

Hi! 👋

I have been using nplusone in https://github.com/hartwork/wnpp.debian.net since 2021 happily — thank you! 🙏

With the last release being of 2018, the project seems dead to me, but maybe this report still has value to someone.

I have a test suite that is all-green on the master branch but GitHub Dependabot sent me a pull request [bumping Django from 6.0.8 to 6.1](https://github.com/hartwork/wnpp.debian.net/pull/1810) which reveals that nplusone [now crashes](https://github.com/hartwork/wnpp.debian.net/actions/runs/31172217369/job/92846322368?pr=1810) in file `ext/django/patch.py` with error:

```
ValueError: too many values to unpack (expected 3, got 4)
```

I'm attaching a backup of the full CI run log for download here: [wnpp-job-logs.txt](https://github.com/user-attachments/files/31088422/wnpp-job-logs.txt).

To give an example crash backtrace, this is the last one from the CI run:

Maybe it helps someone to know that they are not alone with this symptom.

Best, Sebastian

Start in ext/django/patch.py at parse_eager_select and inspect the traceback from test_wellformed_xml in wnpp_debian_net/views/tests/test_rss_feed.py. Compare the Django 6.0.8 and 6.1 behavior around the eager-select metadata, then run the affected test or suite; done means Django 6.1 no longer raises the reported ValueError.
