new maintainer for pypi package

[andreasvc]

Hi @axiak
It seems you're no longer maintaining pyre2; perhaps I could take over? I think this mostly involves handing over the pypi package. Let me know if you want to do this.
Cheers

@axiak could you handle over control of the pypi package to @andreasvc, we are working towards publishing wheels for all platforms
