Fix ZFPY import error (#540)

* Update pyproject.toml

When 

numpy >=2.0.0
from numcodecs.zfpy import ZFPY

raise error [ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject]


The error is caused by zfpy library crashing with recent ABI breaking of numpy udpate. So we'd better force numpy <2.0 unless zfpy update again.


Reference: (https://stackoverflow.com/questions/66060487/valueerror-numpy-ndarray-size-changed-may-indicate-binary-incompatibility-exp)

* Update zfpy.py

Add warning when user import zfpy but with numpy >=2.0.0

* Update pyproject.toml

ensure that the zfpy optional dependency has this constraint.

* Update zfpy.py

* Update numcodecs/zfpy.py
