    tools/python: change 's#' size type for Python >= 3.10
    
    Python < 3.10 by default uses 'int' type for data+size string types
    (s#), unless PY_SSIZE_T_CLEAN is defined - in which case it uses
    Py_ssize_t. The former behavior was removed in Python 3.10 and now it's
    required to define PY_SSIZE_T_CLEAN before including Python.h, and using
    Py_ssize_t for the length argument. The PY_SSIZE_T_CLEAN behavior is
    supported since Python 2.5.
    
    Adjust bindings accordingly.
