/**
 * RIFF/WAVE reader and writer.
 *
 * Covers plain RIFF, RF64/BW64 (the 64-bit extension used for files above 4 GB),
 * `WAVE_FORMAT_EXTENSIBLE`, IEEE float, A-law, µ-law, and IMA ADPCM.
 *
 * WAV is a chunked format, and the chunk sizes are attacker-controlled. Every
 * size is validated against the bytes actually present before it is used, and
 * unrecognised chunks are skipped rather than trusted — a decoder that seeks
 * blindly to a declared offset is the classic way these parsers get exploited.
