Delete generated file createindexlistcython.c

This didn't build anymore with Python 3.9. So I regenerated the file with a more recent version of Cython.

This file is gigantic and the problem can resurface after any Python update. Why don't we dynamically call cython to generate it from the .pyx file? We already print a warning "Boundary setup may take very long! Consider installing cython to speed it up" if the compiled module is missing and pyximport fails, so this would not be a hard dependency. Apparently setup.py calls cythonize if available, so you probably only ran into this problem because cython wasn't installed on your computer?

The current setup works even if Cython is not installed. It just compiles the C file. The generation is right now only triggered when setup is called with --use-cython. The actual python file is apparently never used.

The problem was that apparently some deprecated symbols of the C API disappeared. When you're using the C API of Python it may change in any version but it is a least somewhat stable.

We could change the installation to only generate the cython code if available. I'll push the code. But since pystencils is rather in a frozen "only fix bugs" mode we could also just keep the C file.

I'd prefer not to ship files that can be regenerated. And if someone really does not have cython installed, they'll still be able to use boundaries and will get a warning that tells them to install cython.
