quoije d3e3cbd017 Add RCO and VSMX parsers (menu foundation)

- Lzr: RLZ decompressor ported from JPCSP (for compressed RCO data).
- RcoFile: parses RCO header, entry tree (labels, VSMX blob, image/
  sound/font/object/animation tables, text), and event name table.
- RcoEntrySizes: fixed binary sizes of the 26 object and 11 animation
  record types, needed to locate entries with entrySize=0.
- Vsmx: parses VSMX bytecode (code groups + string tables) and
  disassembles to human-readable opcodes; VsmxCode holds the opcode
  table.
- CLI 'rco' command dumps events, entry tree, and VSMX disassembly.
- Validated against Batman Begins EN/FR menus: full scene graph
  (pages/planes/buttons/groups) and 5585-bytecode scripts decoded.

useless-umd-player

a standalone player for PSP UMD Video ISO images: open a disc, render its real menu, and play the movie (H.264 video + ATRAC3+ audio) with mouse and keyboard/media-key controls.

Status: early development. Currently implemented: ISO 9660/UMD reading, param.sfo metadata parsing, and file listing.

Build

Requires JDK 21 (Gradle auto-provisions it via the Foojay toolchain resolver).

./gradlew build

Run

./gradlew cli:run --args="dump /path/to/disc.iso"
