Rust codec fixtures

The tests decode these hexadecimal files into their exact checked-in bytes; no image is generated while tests run. Unless noted below, fixtures come from the BSD-3-Clause Skia test resources vendored by skia-bindings 0.99.0.

lossy-red.webp was produced once with FFmpeg 5.1.8/libwebp from a solid 8x8 red source (-c:v libwebp -lossless 0 -quality 80) and has SHA-256 7e3aaf1a442b6e69f7706ee5afe0aeacb2d096e384dbb63e792421fe2449cfe8.

The remaining tiny BMP, ICO, WBMP, and lossless RGB WebP files are original MetaCrate byte-level fixtures. Their reviewed bytes are intentionally readable in the .hex files and exercise header fields, row layout, masks, multi-byte integers, and multi-entry selection directly.
