Integrate libmspack's LZX decompressor for Xbox 360 and UE-style compressed data. This replaces the need for external xcompress64.dll which was hanging/crashing on certain files. - Add mspack/ library (lzxd.c decompressor with Gildor's fixes) - Implement memory-based mspack_system for in-memory decompression - Support multiple LZX formats: raw streams, Xbox 360 block format, and Dead Rising 2's per-block format with 4-byte size headers - Add DecompressDeadRisingLZX() with per-block independent contexts to handle the block-based compression correctly Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
