'webImageMediator' should not be nil.

Description

多图显示时，崩溃：“'webImageMediator' should not be nil.” 代码如下：

var imgDataList: [YBIBDataProtocol] = []
for imgUrlStr in allPhotos {
      if let encodedUrl = imgUrlStr.encodeUrl() {
             let imgData = YBIBImageData()
                    imgData.imageURL = URL(string: encodedUrl)
                    imgDataList.append(imgData)
              }
       }
       let browser = YBImageBrowser()
       browser.dataSourceArray = imgDataList
       browser.currentPage = currentIndex
       browser.show(to: self.view)

Environment

• YBImageBrowser version: v3.0.9
• iOS version: Simulator
• Xcode version: Version 10.2 (10E125)

去除 SDWebImage 的依赖（版本需 >= 3.0.4） 这时你必须定义一个类实现YBIBWebImageMediator协议，并赋值给YBImageBrowser类的webImageMediator属性（可以参考 YBIBDefaultWebImageMediator的实现）。
