jpeg2000: fix decoding of mode VSC

[ami_stuff]

-M <key value>
    Mode switch.
    [1=BYPASS(LAZY) 2=RESET 4=RESTART(TERMALL)
    8=VSC 16=ERTERM(SEGTERM) 32=SEGMARK(SEGSYM)]
    Indicate multiple modes by adding their values.
      Example: RESTART(4) + RESET(2) + SEGMARK(32) => -M 38

C:\>opj_compress.exe  -i test.bmp -M 8 -o m8.jp2
