shin: reimplementing the engine of Entergram visual games

shin reimplements a game engine used by Entergram visual games, initially targeting the Switch release of Umineko no Naku Koro ni Saku. It runs original game data and includes a core library and CLI for extracting .rom, .bup, .pic, .nxa and other resources; .snr scenarios have execution tracing rather than decompilation.
