DataX是否支持将.json文件作为数据源读取，有相关的reader插件实现吗？

如题，我看到pull requests有相关的提交，但是为什么这个jsonfilereader没有被官方合并到master分支里呢？感觉json文件是个很常用的需求

Start by reviewing the related pull requests mentioned in the issue and the existing jsonfilereader implementation. Determine the requirements for accepting JSON files as DataX sources and whether the proposed reader fits the project's reader-plugin conventions. Done means the support decision is resolved and, if accepted, the reader is merged into master.
