2.0.0-beta.11

Added

• A rotate button, ahead of the edit button, turns the picture at once
  and writes the turn to the file about a second later by rewriting its
  Exif orientation tag. Nothing is decoded or re-encoded, so the picture
  is the same picture however many times it is turned, and the tag is
  what the preview generator reads, so the new framing follows the file
  into the Files grid and the mobile clients. JPEG only, and only where
  the user may write: no other format carries an orientation this stack
  honours. Written once the user settles rather than once per click,
  since every write makes a version of the file (#49)
• turns on ViewerProps: the quarter turns the viewer is showing on top
  of the file's own orientation, while a rotation is being written. A
  handler that can turn its content should honour it; the rest may ignore
  it, so this breaks nothing that already exists (#49)
• AVIF opens. Every engine the viewer runs in decodes it natively, so it
  is shown from the file itself; nothing in Nextcloud previews it, so
  listing it as preview-supported would have kept it closed everywhere
  (#50)
• MusicXML scores open, .musicxml and the zipped .mxl, drawn with
  opensheetmusicdisplay. The renderer is imported inside the component,
  so it is fetched the first time somebody opens a score and never for
  anyone who only opens photos (#52)
• JPEG 2000 opens where the server renders it. Nothing decodes it in the
  browser, so it sits with the other formats that depend on a preview
  provider, and it needs nextcloud/server#64603, which is in 36 (#53)

Fixed

• A WAV arrives under three different names depending on who wrote it,
  and only one of them was listed, so the other two would not open (#45)
