Can't create big endian dtypes in V3 array

This works with V2 data: ```python zarr.create(shape=10, dtype=">i2", zarr_version=2) # -> i2> ``` But raises for V3 ```python zarr.create(shape=10, dtype=">i2", zarr_version=3) ``` ``` File ~/gh/zarr-developers/zarr-python/src/zarr/codecs/__init__.py:40, in _get_default_array_bytes_codec(np_dtype) 37 def _get_default_array_bytes_codec(...

Device support in `zarr-python` (especially for GPU)

9

**Problem** I would like to load `zarr` data directly onto non-CPU devices (especially GPU). The current approach appears to rely on using `cupy` to load onto `cupy`-supported devices e.g. https://github.com/rapidsai/kvikio/blob/branch-25.02/notebooks/zarr.ipynb....
