[Backend] OME-ZARR support

[rjesud]

Hi, Thanks for developing a very useful library!

Do you have any plans to support the OME-ZARR format?

[Mr-Milk]

Thanks for the issue! Yes, I am aware of the OME-ZARR format. We have support for OME-TIFF at the current stage.

For OME-ZARR, I don't know how well it's used in pathology. It would be great if you could provide some sample data and/or specifications of OME-ZARR in WSI.

This is more relevant for wsidata, so the issue is transferred there.

Probably worth having a look at:

• https://github.com/ome/ome-zarr-py
• https://github.com/ome/napari-ome-zarr/blob/main/napari_ome_zarr/_reader.py

The specification is here:
https://ngff.openmicroscopy.org/latest/

Looks like all metadata we used in wsidata is interchangable to ome specification.
