/**
 * Aztec high-level stream writer.
 *
 * The output is deliberately a `BitWriter`, rather than a byte array: Aztec's
 * text controls and binary-shift lengths are not byte aligned.  This module is
 * also the boundary where JavaScript strings become UTF-8.  Passing a byte
 * view bypasses that conversion and preserves every octet unchanged.
 *
 * The initial state mandated by the symbology is UPPER.  The greedy text pass
 * uses UPPER, LOWER, DIGIT and PUNCT tables, selecting the shortest available
 * latch at each byte.  Bytes without a text-table representation are emitted
 * through the standard B/S (binary shift) escape.  B/S is available from
 * UPPER and makes this a complete, lossless representation of UTF-8 payloads.
 *
