fix for incompatible function pointer types initializing 'PyCFunction' in edgeDB.c

[csoeller]

Addresses issue where compiling on mac (14.7.x) raises errors in edgeDB.c:

PYME/Analysis/points/EdgeDB/edgeDB.c:710:19: error: incompatible function pointer types initializing 'PyCFunction' (aka 'struct _object *(*)(struct _object *, struct _object *)') with an expression of type 'PyObject *(PyObject *, PyObject *, PyObject *)' (aka 'struct _object *(struct _object *, struct _object *, struct _object *)') [-Wincompatible-function-pointer-types]
  710 |     {"addEdges",  addEdges, METH_VARARGS | METH_KEYWORDS,
      |                   ^~~~~~~~
PYME/Analysis/points/EdgeDB/edgeDB.c:712:18: error: incompatible function pointer types initializing 'PyCFunction' (aka 'struct _object *(*)(struct _object *, struct _object *)') with an expression of type 'PyObject *(PyObject *, PyObject *, PyObject *)' (aka 'struct _object *(struct _object *, struct _object *, struct _object *)') [-Wincompatible-function-pointer-types]
  712 |     {"segment",  segment, METH_VARARGS | METH_KEYWORDS,
      |                  ^~~~~~~
...

Is this a bugfix or an enhancement?

backwordscompatible bugfix

Proposed changes:

Typecast explicitly to PyCFunction:

    {"addEdges",  (PyCFunction) addEdges, METH_VARARGS | METH_KEYWORDS, 
...

Compiles fine on mac and PC with these tweaks.

Checklist:

Tested with latest sources from git.
