Added a way to check Block Size, Compression Method, and Compression Level flags to dolphin-tool

Browse Source 
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).
