Right now, the tests are failing with "No module named 'manimpango.cmanimpango'";
it's clearly trying to import the package so it can use it for testing but the
test files are failing to find it (it looks like the "cmanimpango" file is a C
file (along with .pxd and .pyx files) so maybe it's Cython related?).

Is there a way we usually handle this for Python/Cython packages?
