CTRL/SHOC container decoded and first image extracted

We read the game parser in Ghidra and cracked two formats: the resource container and the loading screens.

• CTRL/SHOC/SHDR/SDAT/FILL container confirmed via parser FUN_8002a85c — extractor reassembles named resources.
• .LSC screens are MDEC/BS v2 images (0x3800 magic). We decoded the full "LOADING" screen at 320×256.
• FILL always aligns to 2048 bytes → container designed for CD-sector streaming.
