由于文件size定义为int，32位程序处理大文件可能溢出

[WntFlm]

Please make sure of the following things

• I have read the documentation.
• I'm sure there are no duplicate issues or discussions.
• I'm sure it's due to alist and not something else(such as Dependencies or Operational).

Alist Version / Alist 版本

2.4.3

Describe the bug / 问题描述

使用 alist-windows-4.0-386.exe 下载大文件 （~>5GB）时，size 溢出，下载失败，返回{"code":500,"message":"json: cannot unmarshal number 5175268215 into Go struct field .data.size of type int","data":null}

或许可以把 size 定义成 int64？
