Some numcodecs.zarr3 codecs fail with 3.0.4+ #2900
Description
Zarr version
3.0.4+
Numcodecs version
0.15.0
Python Version
3.12
Operating System
Linux
Installation
See reproducer
Description
The ZFPY and Pcodec codecs (and perhaps more) fail since 3.0.4 because they expect input arrays to be contiguous
