PR to provide necessary files for test_hpiFit

• .fif: 10.2 second long measurement on vectorview with head movement and continuous hpi

• .txt: position file extracted from maxfilter

Thx @RDoerfel

I'm not aware of what y'all are up to, but FYI I spent a lot of time getting MNE-Python's cHPI fitting code to do close to the same thing as Maxwell filter, and the results are here in case you're trying to do something similar:

mne-tools/mne-python#7290

Thank you for the link to the PR @larsoner. We are currently implementing continious hpi fitting for real time head monitoring in MNE Scan.
In your PR I could read that you made some validation. On what data did you test the cHPI fitting? I think this might be interesting for us too.

I used 398 files that I had access to locally. Unfortunately I'm not allowed to share those data files (unpublished WIP data), though :( I am sure that there are other suitable datasets you could use, though.
