Populate ome context

[effigies]

If a file suffix is .ome.tif or .ome.btf or .ome.zarr, it should populate the ome context.

The object needs to follow the protocol bidsschematools.types.protocols.Ome, possibly just using bidsschematools.types.context.Gzip.

For .ome.zarr files, https://github.com/ome/ome-zarr-py is probably the right tool for the job. For .ome.tif/.ome.btf, I think https://github.com/tlambert03/ome-types looks like the right thing. The OME group discussed deprecating their own Python bindings for this project in ome/ome-model#194. It seems like there isn't a lack of options: https://pypi.org/search/?q=ome

Note that our concern is fast metadata access, not data array access.

OME-TIFF is supported in https://github.com/cgohlke/tifffile/blob/master/tifffile/tifffile.py. I suspect our options are Pillow+ome-types or tifffile, and it's just a question of speed.
