希望支持MixFile

### Please make sure of the following things

- [x] I have read the [documentation](https://alist.nn.ci).
- [x] I'm sure there are no duplicate issues or discussions.
- [x] I'm sure this feature is not implemented.
- [x] I'm sure it's a reasonable and popular requirement.

### Description of the feature / 需求描述

https://github.com/InvertGeek/MixFile
mixfile可以利用大厂图床分片储存文件,上传下载不限速
比如可以将微博相册变成储存任意文件的驱动: https://github.com/InvertGeek/mixfileexamplejs

### Suggested solution / 实现思路
电脑安装mixfile之后请求api地址即可
put请求http://127.0.0.1:4719/api/upload?name=文件名称 即可上传文件,上传后会返回分享码
get请求http://127.0.0.1:4719/api/download?s=分享码 即可下载文件
不过文件系统需要alist实现
