    Description

      Bug fixes when reading compressed TIFF files:

      • Some tiles contains wrong data when the compression uses horizontal predictor (`PREDICTOR = 2`). Screenshot attached.
      • Exception throws when a tile using LZW compression does not contain the "End Of Information" (EOI) code. This is invalid, but we observe that it happens in practice.
