feat(build): bump python core to latest (3.16.7) (#204)

Note: I'm using a feat-type commit for this change
because the commit merged in immediately prior to
this commit was mis-labeled and should have been
a feat-type commit. Using "feat" for this commit
will ensure that the previous commit is in fact
published as part of a new release.
