Support Python 3.11

At a minimum, will need to update for PyFrameObject changes.

Looks like there is a change wrt Py_TYPE(obj) = new_type not working - we'll want to fix and add the suggested macro for backwards compatibility:

#if PY_VERSION_HEX < 0x030900A4 && !defined(Py_SET_TYPE)
static inline void _Py_SET_TYPE(PyObject *ob, PyTypeObject *type)
{ ob->ob_type = type; }
#define Py_SET_TYPE(ob, type) _Py_SET_TYPE((PyObject*)(ob), type)
#endif

Py_SIZE(obj) = new_size won't work - we'll want to fix and add the suggested macro for backwards compatibility:

#if PY_VERSION_HEX < 0x030900A4 && !defined(Py_SET_SIZE)
static inline void _Py_SET_SIZE(PyVarObject *ob, Py_ssize_t size)
{ ob->ob_size = size; }
#define Py_SET_SIZE(ob, size) _Py_SET_SIZE((PyVarObject*)(ob), size)
#endif

https://github.com/python/pythoncapi-compat looks potentially interesting; that said, it is pretty easy to maintain our own macros.
