Subject: [PATCH] Drop support for old Python versions (#149)

Specifically, drop support for Python versions older than 3.7, including
Python 2.x.

All of those versions are well beyond their official end-of-life, and
given this is a security-related project, it's reasonable to expect
users to run it in a modern Python environment.
