Support for partial content

## 🏗 Enhancement Proposal

### Pitch
Hi, could you please add support for HttpStatus Code 206 partial content please. My use cases involves binary data and each file uses the Http Range header and with response code 206 (partial content) to separate each chunk. Chunks may change but the all chunks from the same file have the same url. Currently there is no support for this, so it would be awesome if you guys can consider this as additional to the exisiting functionality.

### Platforms affected (mark all that apply)
- [ x ] :iphone: iOS

该 issue 没有列出文件、测试或入口点。首先定位 cache manager 的 HTTP 响应处理，并检查 URL 和缓存 chunk 的存储方式；完成标准是：支持在 iOS 和 Android 上对二进制文件使用 Range headers 的 HTTP 206 响应，同时不破坏现有缓存。

由索引模型根据 Issue 内容生成。
