New dolphin-tool command: "header" -b / --block_size -c / --compression -l / --compression_level Informative RVZ/WIA header2 value "compression_level" is now a s32 instead of a u32, because negative compression is a thing. Speaking of, it is now possible to use negative compression levels in dolphin-tool's convert command (not the GUI, though).
