    Support random access in compressed tiff files. · 0460b1ee

    In compressed tiff files with RowsPerStrip > 1, TIFFReadScanline does
    not support readom access that reading scan lines in arbitrary order.
    This fixes that issue. In such cases, we read the initial scan lines and
    discard them before reading the scan lines of interest. This also
    requires that we read the file in row order in the file (rather than the
    output image).
    
    Test added in parent commit demonstrates the issue. This commit fixes
    that issue.
