ENH: More OPM datasets

[larsoner]

Just noticed that the FLUX folks have

• Cerca: https://doi.org/10.5281/zenodo.17013192
• FieldLine: https://doi.org/10.5281/zenodo.17328849

We could consider adding downloaders for these and showing some basic OPM use cases/processing/functionality potentially. Or at least we could link to these datasets and FLUX from some OPM examples to increase visibility for them and these datasets

@larsoner i want to contribute in these task. But face trouble to find what exactly do? As i am new to this project i need some guides what exactly we are going to do? I readied all about flux, now i need a kick start.

Hello @larsoner sir,
I hope you're doing well. While exploring MNE-Python, I came across a potential contribution opportunity. When running "examples/decoding/decoding_csp_eeg.py", I encountered the following error:
"ImportError: cannot import name 'get_spatial_filter_from_estimator' from 'mne.decoding' "
After investigating, I found a solution to this issue. I’d love to contribute by fixing it, and I see two possible approaches:

• Directly submit a PR with a clear description of the fix, or
• First raise an issue, get your review and assignment, and then proceed with the PR.
  Could you please advise which path you'd prefer I follow?
  By working on this, I’ll gain a deeper understanding of the project’s structure and workflows. In the future, I hope to contribute new features using my skills in AI and ML — especially in areas like decoding pipelines, feature engineering, and model evaluation.
  I’m excited to begin contributing to MNE-Python and hope to identify and resolve more bugs as I continue exploring. Looking forward to your guidance!
  Warm regards,
  Yogesh
