class_docstr: A reader for OME-NGFF files with the .zarr extension. Supports both 'normal' and
  'HCS' storage modes.
  
  OME-NGFF files below spec version 0.4 which are stored on S3/object storage
  should have the zarr.convenience.consolidate_metadata() function run on them
  to provide optimal performance over a network.
  
  Other non-OME .zarr format images may be readable, but are not strictly supported.
