Part/Sketcher: [skip ci] fix build failures with gcc 10 on Fedora

Browse Source 
When using gcc 10 and PyCXX 7.1.4 on Fedora there is an error because the conversion from size_t to Py_ssize_t is ambiguous
See https://forum.freecadweb.org/viewtopic.php?f=4&t=52502

The class Py::Tuple is also incorrectly used here and causes a memory leak
