Writing empty chunks in `build_pyramid`

[m-albert]

Hey :)

Currently fractal_tasks_core.pyramids.build_pyramid doesn't allow passing zarr array creation options such as write_empty_chunks (see https://zarr.readthedocs.io/en/stable/tutorial.html#empty-chunks).

From my point of view this would be useful, see e.g. m-albert/fractal-ome-zarr-hcs-stitching#26.

Happy to create a PR if desired.

Thanks @m-albert ! That's a good point!

If this is needed now, feel free to open a PR. Otherwise, we're slowly deprecating the library functionalities like build_pyramid in fractal-tasks-core in favor of ngio functionality (https://github.com/fractal-analytics-platform/ngio)
