Add mesoSPIM OME-Zarr writer to Tools

[lubianat]

Given yesterday's presentation at the BioVision Center, it seems like it makes sense to add @AlanMWatson's OME-Zarr writing tooling to the documentation

https://ngff.openmicroscopy.org/resources/tools/index.html

Perhaps on Zarr readers & writers or Other tools and libraries

@AlanMWatson can you confirm if https://github.com/CBI-PITT/mesospim_utils/tree/main is the preferred link? If you think it makes sense to be listed, it would be great to have a one-line summary of the functionality. Thank you and congratulations on the nice work!
