  twofish.c:45:1: error: control reaches end of non-void function [-Werror=return-type]
     45 | PyMODINIT_FUNC init_twofish(void) { }
        | ^~~~~~~~~~~~~~
  twofish.c: In function 'PyInit__twofish':
  twofish.c:46:1: error: control reaches end of non-void function [-Werror=return-type]

 We need a stub init_twofish function so the module will link as a proper module.
 Do not import _twofish from python; it will not work since _twofish is not a *real* module
