Patch ZipStore for write_image and write_multiscale method using Dask arrays with storage_options

[snibbor]

Dear all,

Thank you for your work on this project. I am excited to use OME-Zarr in my research. However, I wanted the option to write OME-Zarr to a Zip container, as this format is more convenient for transferring data to remote storage in my workflows.

From reading previous issues and posts, I see that the standard for archiving OME-Zarr images is still under discussion.

During my initial attempts to use ZipStore with the write_image and write_multiscale methods, I encountered failures when using Dask arrays, particularly when the chunks parameter was included in storage_options. The issue stemmed from a duplicate key error in the da.to_zarr method.

To resolve this, I removed the storage_options arguments when working with ZipStore. My tests show that omitting the chunks from storage_options does not affect the chunk size for Dask arrays. I have also verified that all other tests in test_writer.py pass with this change.

Please let me know if there is a better way to do this. I am still learning about the more intricate aspects of Zarr stores and Dask, but I am eager to contribute to and utilize OME-Zarr in my research.

Thank you again,

Jack
