将跨域改为通过GM_xmlhttpRequest获取

介绍

# 我的设置如下
let options = {
    allowTaint: true,
    logging: true,
    useCORS: true,

}
html2canvas(document.documentElement, options ).then( canvas =>{
  var base64Image = canvas.toDataURL("image/png");

})

如果是自己使用webview定义的GM_xmlhttpRequest，可在onload回调参数中新增一个responseBase64用于图片的base64获取
