Support a Vizarr-like API

[keller-mark]

See the Vizarr python API.

We should be able to build a wrapper around the existing VitessceConfig API and expose a more Vizarr-like (potentially drop-in alternative to Vizarr) https://github.com/hms-dbmi/vizarr?tab=readme-ov-file#2-python-api

- import vizarr
+ from vitessce import viewer_api as vizarr 
import zarr

store = zarr.open("./path/to/ome.zarr")
viewer = vizarr.Viewer()
viewer.add_image(store)
viewer
