The scan-for-a-flac-frame-header part of the flac typefinder seems to be a bit
overconfident in its results. I see lots of non-FLAC files typefound as flac,
esp. PDFs.

I guess it should look for consecutive headers or something in that case, or
lower the probability to something appropriately low (such as POSSIBLE?).
