jpeg2000: fix decoding of precints

C:\>kdu_compress.exe -i test.bmp -o precints.jp2 Creversible=yes Stiles={711,393} Cprecincts={128,128}
Note:
    The default rate control policy for colour images employs visual (CSF)
    weighting factors.  To minimize MSE instead, specify `-no_weights'.
Note:
    If you want quality scalability, you should generate multiple layers with
    `-rate' or by using the "Clayers" option.

Generated 6 tile-part(s) for a total of 6 tile(s).
Code-stream bytes (excluding any file format) = 738,792 = 7.898868 bits/pel.
Layer bit-rates (possibly inexact if tiles are divided across tile-parts):
        7.898868
Layer thresholds:
        0
