For correct testing, do we already have a CfRadial1 file with n_points dim in the open-radar-data repo?

Update: I'm adding one, see above.

This looks great - nice fix @kmuehlbauer

[kmuehlbauer]

I'll add a test, to work against any regression.

[kmuehlbauer]

The added test will need new open-radar-data v0.3 which will be in conda-forge within the next hours. So maybe we need to rerun the CI later if this fails now.

v0.3 has already landed 🎉
