MNT: support python 3.10

tacaswell · tacaswell · commit 405c6dec7987 · 2020-05-29T11:02:35.000-04:00
In python/cpython#20290 CPython changed `Py_TYPE` from a macro to an inline function. This requires a code change to us `Py_SET_TYPE` instead when using `Py_TYPE()` as a lvalue in c code. In python/cpython#20429 CPython changed `Py_SIZE` from a macro to an inline function. This requires a code change to us `Py_SET_SIZE` instead of using `Py_SIZE` as a lvalue in c code.
