prospector crashes on startup if a recent pyroma is installed

[njsmith]

If I install pyroma==2.0, then prospector works fine.

But pyroma 2.1 was released ~a year ago, and it removed the attribute pyroma.ratings.PEP386Version, which prospector unconditionally references during startup (if pyroma is installed). If I have pyroma==2.1 or pyroma==2.2, then I get:

$ prospector --help
Traceback (most recent call last):

AttributeError: module 'pyroma.ratings' has no attribute 'PEP386Version'

Note that it doesn't matter whether prospector has pyroma enabled -- if you have pyroma and prospector in the same venv, then prospector doesn't work at all.

Prospector now uses the latest pyroma version. It'll be integrated into version 0.12.9. Closing this issue since it's fixed.
