Breaks when py is not installed

[JelleZijlstra]

pytest 7.2.0, released just now, makes py an optional dependency (https://docs.pytest.org/en/stable/changelog.html#pytest-7-2-0-2022-10-23), but pytest-sugar still relies on it, leading to a crash if py is not installed:

(Invoking pytest in a env with pytest-sugar but not py installed.)

I'm getting the same error, and the problem indeed goes away when installing py.

The fix is pretty simple - @Teemu does #242 look OK?

This looks good to me. My apologies for the earlier confusion!
