I fixed most of the CI failures. The remaining 2 failures appear unrelated.

I support this. It is in line with the decision made at the Copenhagen 2023 meeting which was: HDF5 and Zarr are preferred formats for new multi-dimensional data.

It looks like we dropped the ball on the wording in #1614, but I do think the decision should hold, nonetheless.

That's shaping up nicely! Please complement with a PR against bids-examples which would demo some fake dataset with .ome.zarr . FWIW -- here I am creating one but scripting so I could easily recreate etc

Thanks @yarikoptic. There was already a bids-examples dataset with an .ome.zarr so I pushed a commit that references it.

@effigies - we have 2 approvals. This is a tiny PR with HUGE potential consequences. I would love us to proceed on it regardless since I feel it is the right thing to do!
