Erich Blume 33463764d1 Add QArt Tuner: QR code art generator with interactive web UI 
Single-file Go tool implementing the QArt technique (Russ Cox, 2012)
using only the public rsc.io/qr API. Generates QR codes whose data
modules form a recognizable image by exploiting error correction
freedom via GF(2) Gaussian elimination.

Includes a web UI with live-updating sliders for version, mask,
rotation, dx/dy offset, and scale. Keyboard shortcuts for rapid
iteration. Also works as a CLI for batch generation.
