Pull Request Overview
This PR adds single-scale OME-NGFF (0.4) metadata support when creating zarr arrays. The changes enable proper OME-NGFF metadata generation and improve the blockwise processing workflow.
- Adds a new function to generate OME-NGFF v0.4 compliant metadata for single-scale datasets
- Updates the blockwise processor to use NestedDirectoryStore and apply metadata to zarr groups
- Improves progress tracking and error handling in the processing pipeline

The name field is set to an empty string. Consider making this configurable through a parameter or providing a meaningful default name.

The hardcoded values for translation and units should be made configurable or derived from existing configuration parameters to maintain consistency.

The magic index [1] for block.block_id is unclear. Consider adding a comment explaining what this index represents or using a named constant.
