+ISO 18004 requires `0b11101100_00010001` (`0xEC11` / `60433`) be used as
+padding bytes at the end of a message, but you can customise this otherwise
+dead space with any 16-bit value (`0x0000` – `0xFFFF`).

+const code = generate(mode.alphaNumeric('LEAN-QR LIBRARY'), {

+Combining a large minimum version with a trailer of `0x0000` will reveal the
