Add Rust revival engine for Super Skidmarks

Cross-platform (Windows/macOS/Linux) engine that plays the original
Amiga data straight from the ADF images:

- ADF (OFS/FFS), LHA and CrunchMania (CrM!/CrM2) readers
- Track decoding: 24 tracks of 1024x512 16-colour planar art, height
  maps and lap gates on an isometric ground plane
- Vehicle decoding: 8 cars, 32 headings x 25 tilt frames of 64x32
  AGA sprites
- Reconstructed handling, AI, race rules, menus and synthesised sound
  (disk 1 with the executable, palettes and audio is not in the set)
- info/extract/bench/trace/render tools, format notes, CI builds
