/**
 * MP3 decoder.
 *
 * Walks the frame sequence, assembles main data through the bit reservoir, and
 * runs each granule through the full Layer III chain:
 *
 * ```
 * side info -> scalefactors -> Huffman -> requantize -> reorder
 *   -> stereo -> alias reduction -> IMDCT -> frequency inversion
 *   -> polyphase synthesis -> PCM
 * ```
 *
 * ## Gapless playback
 *
 * An MP3 never contains exactly the audio that went in. The encoder's
 * filterbank needs priming, so it prepends silence, and it pads the final frame
 * out to a whole 1152 samples. LAME records both figures in a tag, and honouring
 * them is the difference between a seamless album and a click between every
 * track. When the tag is present those samples are trimmed; when it is absent a
 * conservative default delay is used.
