In a type-safe world, this is correct because:
 decodeFile only reached if JBIG2_FILE_STREAM
 JBIG2_FILE_STREAM unused.
 JBI2_SEQUENTIAL_STREAM only in decodefile
 JBI2_SEQUENTIAL_RANDOM only in decodefile
so only embedstream remains. Wish this were a enum to start with, compiler might
catch passing an aribitrary int instead of the enum to something like new
CJBIG_Context(..., 3, );
