update numpy flags

[jan-janssen]

The numpy flags changed:

NPY_FORTRAN -> NPY_ARRAY_F_CONTIGUOUS
NPY_WRITEABLE -> NPY_ARRAY_WRITEABLE
NPY_ALIGNED -> NPY_ARRAY_ALIGNED

Thanks for the contribution. It’s failing the CI on Python 3.8 on macOS, presumably because the version of numpy there predates the change. Is there a way to get this to work in both cases, eg with an#ifdef?

From a quick look wrapping your changes in #if NUMPY_VERSION > 1.7 and leaving my old code in an #else branch should do the job.

Unfortunately, there are still some more issues, it seems also PyArray_INT is now replaced with PyTypeNum_ISINTEGER and the usage of PyArrayObject changed as well. The error I currently get is:
