mrwnslz f4b8bcc891 Podcasts: Kapitel, Shownotes und Transkripte für die Apps
- Feeds liefern jetzt Podlove-Kapitel (psc:chapters), Podcasting-2.0-Kapitel
  (podcast:chapters, JSON-URL) und Transkripte (podcast:transcript, auch
  mehrere); als Beschreibung wird content:encoded bevorzugt.
- Bekannte Folgen werden beim Aktualisieren nachgezogen, aber nur die Zeilen,
  die sich wirklich geändert haben.
- Neuer Endpunkt GET /podcasts/episodes/<id>/ mit bereinigten Shownotes,
  Zeitmarken, Kapiteln, Transkripten und Fortschritt. JSON-Kapitel werden
  einmal serverseitig geholt (nur öffentliche Adressen, max. 1 MB) und an
  der Folge gespeichert.
