ljpeg: support files with interval in MCU-rows different than 0

I will attache ljpeg files with "restart interval in MCU-rows" option set to 0, 1, 25 and 50. Currently FFmpeg can correctly decode files when this option is set to 0.
I created attached files with "ImageConverter? Plus" and then loaded them to "PICTools Apollo" to confirm that the files are correct.
