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).

This is intended to catch WIA files which have been created using
wit's default parameters (40 MiB block size), once the WIA PR is
merged. The check does however also work for GCZ files – not that
I think anyone has a GCZ file with a block size that large.
