FYI: stubs are being added to typeshed

[richardnias]

Hi,

I just wanted to write here to keep the maintainers aware that I've opened a PR to add a types-untangle package: python/typeshed#9402. I haven't spent a lot of time with the internals of untangle so there might be mistakes, but for my purposes it works (mypy passes in my project when using the stub file) so I thought I'd share it.

Thanks for the library!
