1.6 - Starting version for 2023/2024 edition of the course

This version includes a large amount of further improvement from feedback from Martij Kluitenberg.
Numbering in some sections has changed, warranting a new version number.

As usual, the release contains two versions of the lecture notes:

• aom-tg compiled with the TeX Gyre font family
• aom-od compiled with the Open Dyslexic font family

The content is identical, feel free to pick the version you find more readable
