Install problem on Python 3.11

[stalker314314]

Hi, When trying to install 0.0.4 on Debian (12, Bookwork) with Python 3.11, I get something like:

install.log

When cloning project and doing python3 setup.py build, I get:

running build
running build_py
running build_ext
building 'gtfspy.routing.label' extension
x86_64-linux-gnu-gcc -Wsign-compare -DNDEBUG -g -fwrapv -O2 -Wall -g -fstack-protector-strong -Wformat -Werror=format-security -g -fwrapv -O2 -fPIC -I/usr/include/python3.11 -c gtfspy/routing/label.c -o build/temp.linux-x86_64-cpython-311/gtfspy/routing/label.o
cc1: fatal error: gtfspy/routing/label.c: No such file or directory
compilation terminated.
error: command '/usr/bin/x86_64-linux-gnu-gcc' failed with exit code 1

To workaround this, I need to remove routing extension and only then I can build it. Any idea how to "fix" routing extension to be able to tell people to just pip install it (I have tool that depends on gtfspy)

Hi @stalker314314,

Great to see that there is interest towards using the gtfspy-package.

Unfortunately, I have not had the time in the past (years) to maintain/support this package, and I don't have a quick answer to provide you with. @rkdarst or @jweckstr: Do you have any top-of-mind idea on this?

In any case, if you (@stalker314314) can up with a fix that solves the issue, we're happy to receive a PR so that others can benefit from your work as well.
