Plugin is not working on Python <3.7, but this is not mentioned in readme #1

Python starts from 3.7? Seems, plugin fails on Python 3.6.8 on line: from __future__ import annotations Is it possible to add information about requirements in readme?

Thanks for the report! Version 0.0.2 of the plugin supports python 3.6 + readme has badge about it :)
