Description
Previously something like z[()] where z is a () shape array would return a scalar and now returns a one-elem array e.g., np.array(1) instead of np.float64(1.0)
Steps to reproduce
v3:
import numpy as np
import zarr
z = zarr.open_group('foo.zarr')
z.create_array("bar", dtype=float, shape=())
z["bar"][...] = np.array(1) # why doesn't [:] work?
z["bar"][()] # arrayv2:
import numpy as np
import zarr
z = zarr.open_group('foo.zarr')
z.create_dataset("bar", dtype=float, shape=(), data=np.array(1))
z["bar"][()] # np.floatAdditional output
