复现步骤：
1.调用fromDataUrl设置一个初始图片
2.采用canvas.toBlob()保存图片
报错信息：
Failed to execute 'toBlob' on 'HTMLCanvasElement': Tainted canvases may not be exported。

经查询后，跟跨域有关：https://blog.csdn.net/qiphon3650/article/details/80087987

跟踪源码后发现依赖的signature_pad的版本是3.0.0-beta.2，代码未设置image.crossOrigin = 'anonymous'，个人也已在本地添加该行代码进行验证，完美保存！

请问是否可以更新下signature_pad的依赖版本，然后升级个版本？
