tox-pyenv breaks with tox 4.0rc1

[neutrinoceros]

Looks like tox-pyenv relies on the py library but doesn't declare it explicitly as a dependency

tox-pyenv/tox_pyenv.py

Line 47 in 7391610

import py

Since tox itself is dropping py, tox-pyenv breaks with the latest release candidate.

Ping @gaborbernat as the common maintainer in both projects.

The maintainer of this library is @stavxyz, so he'll be able to answer you. I'm just backup. If someone wants to put in a PR for supporting 4.0 can review and accept but will not do the work myself. In the meantime, you can pin to <4 or drop using this plugin.
