/**
 * AIFF and AIFF-C reader and writer.
 *
 * Apple's answer to WAV, and structurally its mirror image: the same
 * chunk-plus-size layout, but big-endian throughout, with the sample rate stored
 * as an 80-bit extended float — a format essentially nothing else in computing
 * still uses.
 *
 * AIFF-C adds a compression identifier. The one that catches people out is
 * `sowt` ("twos" backwards), which means *little-endian* PCM inside a big-endian
 * container. It is what macOS writes by default, so any reader that assumes
 * big-endian samples plays real-world Apple files as loud static.
