**Port-Konfiguration:**
- Individuelle Benennung jedes Ports möglich
- Aktivieren/Deaktivieren von Ports
- Persistente Speicherung der Konfiguration in `portconfig.json`
- Globale Blinkfrequenz für fehlerhafte Ports einstellbar (in ms)
- Persistente Speicherung der Konfiguration in `portconfig.json`, inklusive Blinkintervall
