mlbis: matching Mario & Luigi: Bowser's Inside Story decompilation

mlbis reconstructs the Nintendo DS game Mario & Luigi: Bowser's Inside Story as C/C++ source intended to match the retail ROM byte for byte. Its tooling compiles units with CodeWarrior, compares functions and data objects against delinked ROM targets, and relinks modules for byte comparison.
