Thanks for kicking this off. We will also need to do more work in the future, as v3 eventually gains more features that don't get backported to v2. For example, I don't know if we can already use the v3 unfinished sharding code to do what preffs does, concatenating multiple target byteranges to a single chunk for some of the data chunks. I suppose when v3 is finished and released, we could decide to drop v2 completely here, but I suspect it will be around for quite some time yet. |

Somehow I messed up my fork here. I'm going to close this PR and I'll reopen. |

This PR experiments with adding Zarr v3 support to Kerchunk.
In most cases, this simply requires passing the
zarr_versionparameter to thezarr.groupconstructor. The primary exception is incombine.pywhere lots of v2 metadata keys are hard coded. I have not tried to tackle that part of the codebase yet.If you are reviewing this, I suggest starting with the hdf5 translator and the Python 3.10 GitHub action.
