Python 3.12 support

[virnik0]

Description

I am trying to build pycoral for use on Ubuntu 24.04 with Python3.12, x86_64 arch.

I have tried few diferent forks, but the latest one and most promissing was faranick's.

Downgrading Python to version 3.11 is not an option given how hardwired 3.12 in the system is. I tried - and only result was corrupted python install and messed-up dependencies (easy to solve with zfs snapshot revert).

I do have tflite_runtime-2.17.0-cp312-cp312-linux_x86_64.whl wheel build from faranick, and libedgetpu1-max_16.0tf2.17.0-1.ubuntu22.04_amd64.deb (which seems to be working fine on Ubuntu 24.04) from the same author. But I am missing pycoral. While I was able to rebuild libcoral and verify that my coraltpu works, I am unable to use python bindings in anything relevant to it due to absence of pycoral.

I have dowgraded bazel to version 5.4.1, otherwise the build would fail much sooner.

It does. The dev provided link to his git repo. I did as well.
