urh fails to build with Python 3.13.0a5.

src/urh/dev/native/lib/airspy.cpp: In function ‘int __pyx_f_3urh_3dev_6native_3lib_6airspy_start_rx(PyObject*, int)’:
src/urh/dev/native/lib/airspy.cpp:21308:3: error: ‘PyEval_InitThreads’ was not declared in this scope; did you mean ‘PyEval_SaveThread’?
21308 |   PyEval_InitThreads();
      |   ^~~~~~~~~~~~~~~~~~
      |   PyEval_SaveThread

According to https://docs.python.org/3.13/whatsnew/3.13.html:

Remove PyEval_InitThreads() and PyEval_ThreadsInitialized() functions, deprecated in Python 3.9.
Since Python 3.7, Py_Initialize() always creates the GIL:
calling PyEval_InitThreads() did nothing and PyEval_ThreadsInitialized() always returned non-zero.

Testing and mass rebuild of packages is happening in copr.
You can follow these instructions to test locally in mock if your package builds with Python 3.13:

Let us know here if you have any questions.

Python 3.13 is planned to be included in Fedora 41.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.13.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires),
so if this package is required a lot, it's important for us to get it fixed soon.

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work around it on our side.
