Projektdateien per SSH/rsync auf einen Raspberry Pi kopieren.
Aufruf:
bash tools/upload_to_pi.sh --user BENUTZER --host HOST \
--remote-dir /home/BENUTZER/halloween [--source ORDNER] [--install-service] [--apply]
Ohne --apply wird nur der geplante Aufruf angezeigt; es gibt keine Verbindung
zum Pi. --apply legt den Zielordner an und kopiert die Dateien. Alte Dateien
auf dem Pi werden nicht gelöscht.
--install-service richtet nach dem Upload einen systemd-Autostart ein. Dazu
muss die Python-Umgebung auf dem Pi bereits vorbereitet sein; sudo wird dort
benötigt. Ohne --apply wird auch der Dienst nicht installiert.
