We need to have a go to command line tool for BIG archive packing and unpacking.

For Mod Builder, we currently use the https://github.com/TheSuperHackers/GeneralsBigCreator, which works fine for BIG archive creation. It can also read in the BIG Archive, but cannot extract it via command line.

But I would like to have this tool deprecated, and reimplemented closer to the game engine internals, so that the tool implementation is closely tied to what the game client understands.
