There is no way to preserve ID3v2.4 replaygain information (in the 'RVA2' frame format)

      I make heavy use of replaygain, and store it in MP3 files in the RVA2 frame (generated with the 'mp3gain' tool). Despite having 'RVA2' (or '~id3:RVA2') in picard's preserve tags setting, the RVA2 frames are removed when I save the file.

      Before saving, the file tags look like this (printed with mutagen-inspect):

      -- /home/cwalton/temp/temp/アルトノイラント/届け、我らの頭上に在りし水なき海へ/01 - アルトノイラント - 静かの海:鮮やかな記憶.mp3
      - MPEG 1 layer 3, 182891 bps, 44100 Hz, 108.83 seconds (audio/mp3)

      After saving, the two RVA2 frames are no longer present.
