Fix CI failures on Github (#94)

* Accommodate FrameLocalsProxy introduction in Python 3.13

The `frame.f_locals` is now a write-through proxy object of type
`FrameLocalsProxy`; see PEP 667. This fix is based on
zopefoundation/zope.interface#294 and
specifically on
zopefoundation/zope.interface#294 (comment).

Fixes #91.

* add 3.13 to checked ci

* use macos-12 to test macos (later versions dont seem to build python correctly)
