Importing numcodecs fails with zfpy 1.0.1.post0 installed #892

With the released wheels for numcodecs 0.17.1, zfpy 1.0.1.post0 and NumPy 2.5.4 on CPython 3.12.11 (macOS arm64), this fails before any codec is used:

import numcodecs

The traceback ends in numcodecs/zfpy.py at tuple(map(int, version("zfpy").split("."))), with ValueError: invalid literal for int() with base 10: 'post0'. I expected the post-release of 1.0.1 to pass the existing compatibility check.

I found this in the Python 3.13 Linux CI job for #891, where the same exception stopped collection, and reproduced it independently with the public release. Codex assisted with diagnosis and reproduction.
