Python 3.12 compatibility

[Zethson]

Hi,

my CI job with Python 3.12 fails because of:

Caused by: Failed to fetch wheel: blosc==1.11.1
Caused by: Failed to build: blosc==1.11.1
Caused by: Build backend failed to build wheel through build_wheel() with exit status: 1

This seems to be an issue with the sdist. I can compile from a git-checkout on the 1.11.1 tag, but get this failure building from the sdist (both pulling from pypi and if I make the sdist locally).

pip install git+https://github.com/blosc/python-blosc.git@v1.11.1

also works for me.

[tacaswell]

The issues seems to be with the bundeled version of blosc, setting USE_SYSTEM_BLOSC=1 gets the sdist to build for me as well with py312.

Ok. It looks like a new release is needed soon. Thanks for the hint.
