TypeError in _FillValue handling

[groutr]

I am reading weather netcdf files and frequently see this error:

only 0-dimensional arrays can be converted to Python scalars
Traceback (most recent call last):
  File "<...>/kerchunk/hdf.py", line 478, in _translator
    fill = encode_fill_value(fill, dt or h5obj.dtype)
  File "<...>/kerchunk/utils.py", line 236, in encode_fill_value
    return int(v)
TypeError: only 0-dimensional arrays can be converted to Python scalars

h5py is returning a 1D array with a single integer element that is causing encode_fill_value to choke.

One possible solution:

if v is None:
    return v
v = np.asanyarray(v, dtype=dtype)
v = v.squeeze()  # Convert single value 1D arrays to 0D array

at the top of encode_fill_value.
