What's new
Much of the issues described in 9, including:
- move some helper functions to new module `utils`
- create new module `ome_zarr`
- add new class `ome_zarr.Image` to represent a single image
(implements most of the well-level functionality in `hcs_wrappers.plate`,
and in addition adds a few new tricks, like automated scaling of intensity
and label arrays)
- mark `hcs_wrappers` classes as "legacy" in the documentation
