  • add support for zarr-python>=3
  • drop support for xarray<0.19.0
  • defer to xarray/zarr for handling whether metadata is consolidated or not. This may lead to additional warnings in the case of non-consolidated metadata. Performance may also be slower when dumping metadata associated with a pure zarr (not xarray-openable) dataset and using zarr-python<3.

Ideally would prefer to use KeyError for both zarr v2 and v3, instead of using `ValueError for zarr v3 as is currently implemented in this PR. Raised an issue on xarray: pydata/xarray#9970
