I'm having a bit of trouble reviewing this because of the formatting change. Can we remove those and maybe do them in another PR if necessary? 🙏

#74 enabled us to read from local
stack_chunkwhen available. And some of CPython 3.13+ tests were segfaulting since then, see #85 for examples. This PR fixes them.Since CPython 3.13, objects other than code objects can exist as "executable" of an internal frame, see python/cpython#105727. This required us to iterate over frame objects checking the type, and we need to make sure those frame addresses are resolved using
stack_chunkor copied properly.
