希望支持curl代理配置

[buexplain]

F:\swow>box.exe self-update
[ERROR] cURL error 56: OpenSSL SSL_read: Connection was reset, errno 10054 (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://raw.githubusercontent.com/hyperf/box/master/pkgs.json
App\PkgDefinitionManager::getPkgs(): Return value must be of type array, null returned

不知道支持curl的代理后能不能解决问题。
