使用lfs追踪git的大文件

当文件大于100M时，git无法正常提交，此时可以使用lfs进行追踪

1. 安装lfs

git lfs install

2. 创建.gitattributes文件
   将大文件的后缀添加上

*.fbx filter=lfs diff=lfs merge=lfs -text
*.pdf filter=lfs diff=lfs merge=lfs -text
*.mp4 filter=lfs diff=lfs merge=lfs -text
*.avi filter=lfs diff=lfs merge=lfs -text
*.zip filter=lfs diff=lfs merge=lfs -text
*.rar filter=lfs diff=lfs merge=lfs -text
*.7z filter=lfs diff=lfs merge=lfs -text
*.db filter=lfs diff=lfs merge=lfs -text

3. 这时就可以提交大文件了
