From 24d85ff767c43235d9a9bc90f66203b5a0791479 Mon Sep 17 00:00:00 2001
From: Yegor Yefremov <yegorslists@googlemail.com>
Date: Sun, 30 Jun 2024 21:54:14 +0200
Subject: [PATCH] Remove packaging module dependency
codegen requires only Version class functionality. Hence, it is
sufficient to include version.py and _structures.py files from
the packaging module.
