Come up with the equivalent of this:

    public Cms.Profile GetProfile ()
    {
        Marker m = FindMarker (IccProfileSignature);
        string name = IccProfileSignature.Name;
        try {
            if (m != null)
                return new Cms.Profile (m.Data, name.Length, m.Data.Length - name.Length);
        } catch (System.Exception e) { 
            System.Console.WriteLine (e);
        }
        
        FSpot.Tiff.Header exif = GetExifHeader ();
        if (exif != null) 
            return exif.Directory.GetProfile ();

        return null;
    }  

Preferably without introducing an lcms dependency in Taglib#. Should be doable by exposing it as a byte array.
