Fix build error with Python 3.10 build on Windows

acozzette · acozzette · commit 203c593b9681 · 2022-01-10T16:55:04.000-08:00
The Windows build for Python 3.10 is giving us an error about ssize_t
being undefined, so this commit fixes the problem by replacing it with
Py_ssize_t, which is consistent with what we do elsewhere in the file.
