可用于现代浏览器及小程序环境，用来生成svg格式的二维码，输出为svg格式的字符串或其base64形式。

用法：

import qrCodeSVG from 'miniprogram-qrcode-svg';

const qrcode = qrCodeSVG("http://github.com/", {
  padding: 4,
  width: 256,
  height: 256,
  color: "#000000",
  background: "#ffffff",
  ecl: "M",
}).toSVG();

选项

• ecl: error correction level: L, M, H, Q
• typeNumber: QR code type number from 1 to 40, default: 0 for auto detection
• padding: white space padding, 0 for no border
• width: QR Code width in pixels
• height: QR Code height in pixels
• color: color of modules (squares), color name or hex string, e.g. #000000
• background: color of background, color name or hex string, e.g. white
