Consider supporting pathlib.Path within Dask Arrays .to_zarr(...) method #8006
Description
Not sure if this should be raised in maybe the zarr repo, and I've looked through previous issues and couldn't find anything regarding this - it's feels like the Dask Array .to_zarr(...) method could support pathlib.Path (directly, i.e. without having to turn it into a str):
Dask Version: 2021.7.2
>>> import pathlib, dask.array as da, numpy as np
>>> da.from_array(np.array([1])).to_zarr("file.zarr") # works
>>> da.from_array(np.array([1])).to_zarr(pathlib.Path("file.zarr")) # yields:

TypeError: argument of type 'PosixPath' is not iterableIn particular I've noticed that Dask DataFrame .to_parquet(...) supports this:
>>> import pathlib, dask.dataframe as dd, pandas as pd
>>> dd.from_pandas(pd.DataFrame({"a": [1]}), npartitions=1).to_parquet(pathlib.Path("file.parquet")) # worksMany thanks for these awesome libs!
