cache mp4 video file not played by VideoPlayer package on ios

## 🐛 Bug Report

I use flutter cache manager last version to cache images and videos it works well on android also on ios it cache and shows image files perfectly, but cached mp4 or .ts video files can not be played by the Video player package on ios,
is it required any extra configuration or permission on ios?

**Platform:**
- [x] :iphone: iOS

该 issue 未指出任何 repository 文件或测试。首先在 iOS 上复现缓存的 mp4 和 .ts 播放，对比缓存文件和未缓存文件，然后检查缓存管理器和 VideoPlayer 集成，以确定失败是由缓存还是 iOS 配置导致的；当缓存视频能够在 iOS 上成功播放，或所需的限制已记录时，即视为完成。
