Raw binary save file parser for No Man's Sky.

Reads save.hg files directly from disk:

  1. Detect format (plaintext JSON vs LZ4 compressed)
  2. Parse sequential LZ4 blocks (magic 0xFEEDA1E5), decompress, concatenate
  3. Deobfuscate JSON keys using MBINCompiler's mapping.json
  4. Deserialize into typed Rust structs via serde

Also handles metadata verification (mf_save.hg) via XXTEA + SHA-256.
