Kerchunk-Like functionality

[alex-s-gardner]

This is not an issue with Zarr but I suspect @meggart and other Zarr.jl contributors are the right people to comment on developing Kerchunk-Like functionality for Julia.

Progress has been made on this issue:

• A Julia wrapper for xarrays, so we get access to all of the xarray features in Julia: https://github.com/meggart/PyYAXArrays.jl
• A Julia wrapper for Python's fsspec library (which also implements a Kerchunk reader): https://github.com/asinghvi17/FSSpec.jl
• A Julia FSSpec reader and virtual store for Zarr https://github.com/JuliaIO/Kerchunk.jl
