Aborted tests with Python 3.13.0b2

[arkamar]

I tried to test nh3-0.2.17 with Python 3.13.0b2 and the test suit is aborted with following output:

python3.13 -m pytest -vv -ra -l -Wdefault -Werror::pytest.PytestUnhandledCoroutineWarning --color=yes -o console_output_style=count -o tmp_path_retention_count=0 -o tmp_path_retention_policy=failed -p no:cov -p no:flake8 -p no:flakes -p no

The actual error is:

python: ./Include/internal/pycore_object.h:284: _PyObject_Init: Assertion `_PyType_HasFeature(typeobj, Py_TPFLAGS_HEAPTYPE) || _Py_IsImmortal(typeobj)' failed.

and typeobj is:

$1 = (PyTypeObject *) 0x55e97638b580 <_PyExc_TypeError>

So this is probably PyO3/pyo3#4311.
