Python 3.13 - support in github, but not released on pypi?

[imchipwood]

When using the latest antlr4-python3-runtime from pypi.org (4.7.2), I get a ModuleImportError for trying to import from typing.io.

Looking at the repo, though, the issue is fixed by importing from typing on Python versions >= 3.6.

This change is old... why is it not part of the released package on pypi.org?
