add Changelog and Version info to documentation

apply flake8, remove Python 3.10 Syntax
make sure that the package works with older Python versions: - replace matches with if-then-else - Replace "|" with "Union" - Remove "TypeAbbrev" Make sure taht flake8 produces few warnings. Add github action for automatic checks.

 als Windows-Service auf einem eigenen Rechner installiert und überwacht dort ein bestimmtes Verzeichnis.
 Bei Änderungen an Dateien in diesem Verzeichnis (Hinzufügen, Ändern, Löschen) werden die Dateien verarbeitet
 und die Ergebnisse an APplus gemeldet. Dafür werden DB-Operationen aber auch SOAP-Calls benutzt.
