Dennis Heimbigner a5cae51efc Turn on the xarray convention for NCZarr format
re: https://github.com/pydata/xarray/issues/6374

As a result of a discussion about Xarray (see above issue),
I decided to turn on the xarray convention for NCZarr datasets
where possible so that xarray can read a larger set of nczarr
generated datasets.

This causes the following changes:
* If the user wants to generate a pure zarr file, then the mode "zarr" must be explicitly used; it is no longer the case that "mode=xarray" or mode="noxarray"
implies "mode=zarr".
* It is still the case that "mode=noxarray" will turn off the XArray convention.

The following conditions will cause ''_ARRAY_DIMENSIONS'' to not be written.
* The variable is not in the root group,
* Any dimension referenced by the variable is not in the root group.
