to_file / dump / etc should support Zarr with ZipStore specifically #1683
Description
Related to #293
Zarr has a number of nice benefits over regular netCDF4. However, it comes with a large downside, which is that the Zarr hierarchy is just files. This makes the files visible to the operating system, which makes moving them around a lot slower. The solution here is to use a 0-compression ZipStore instead. This'll render the zarr store intransparent, which makes e.g. copying significantly easier.
If we support zarr, we should perhaps default to a ZipStore (and also make sure it's easily supported in reading the data back into Python).
I see there's an old issue of mine still open at xarray: pydata/xarray#4076
