Zuerst erstellen wir eine `GzipRequest`-Klasse, welche die Methode `Request.body()` überschreibt, um den Body bei Vorhandensein eines entsprechenden Headers zu dekomprimieren.

Wenn der Header kein `gzip` enthält, wird nicht versucht, den Body zu dekomprimieren.

Auf diese Weise kann dieselbe Routenklasse gzip-komprimierte oder unkomprimierte Requests verarbeiten.
