Dear Kang Seonghoon씨
i  Just start evaluation j40 decoder for embedded purpose.
Attached tmp.jxl picture file that compressed libjxl/tools/cjxl -e 5 
[tmp.zip](https://github.com/user-attachments/files/18106611/tmp.zip)

i got 
$ ./dj40 tmp.jxl
Error: Decoding failed (box?) during j40_next_frame

So, letme know what use cjxl option that can decode j40?
