Obfuscated PBOs carry decoy files: a valid ODOL or PAA header followed by garbage. Reading them panicked or aborted the process on allocations of up to 17 GB. Now they fail with an error.

• LZO: lzokay-native 0.2.1's bounded decompression. ODOL arrays use decompress_bounded with the expected size, PAA mipmaps (DXT1, DXT5) decompress_all_bounded, limited to the mipmap's 4x4 blocks (8 bytes each for DXT1, 16 for DXT5). lzokay 0.1 panicked on matches reaching before the start of the output and allocated the expected size up front.
• decompress_lzss, raw ODOL array reads and array capacities grow with the data instead of trusting the count. Default-filled condensed arrays are capped at 2^24 elements (the largest LOD seen has 669,004 vertices). Element count times size is checked for overflow.
• AnimationRTWeight: more than 4 bone weights is an error, it indexed past its 8 bytes.
• PBO entries: compressed data with bytes after the LZSS stream is kept as stored, like other undecodable entries, instead of panicking.
• Tests: corrupted and truncated test models (fail on main with the lzokay panic), a PBO with garbage compressed entries (fails on main at the assert_eq!).

Checked against Arma 3 (6,682 models, 20,817 textures) and 150 mods (~28,000 models, ~320,000 textures):

• The same models and textures load as before, with the same mipmap bytes. ODOL::from_path is as fast as before.
• All 5,496 decoy models (3CB Factions, Pr.1204, Tiger, Stargate, Blastcore) fail with an error: no panics, no allocation over 512 MB.
• Decoy textures: 442 that panicked and 14 that decoded to more data than the texture holds now fail with an error.

Independent of #46.
