Support of SOCKS proxies

[lazygorilla]

Hello, is there a SOCKS-proxy support? I see that I can use HTTP/S proxies. When will you implement the support of SOCKS4/5?

I found it is support the SOCKS proxy in Windows10, you can test like this.

proxyURL, err := url.Parse("socks5://127.0.0.1:1080") // Proxy URL
if err != nil {
    log.Panicln(err)
}

resp, err := grequests.Get("http://www.levigross.com/",
    &grequests.RequestOptions{Proxies: map[string]*url.URL{
        "http": proxyURL,
        "https": proxyURL,
    }})

if err != nil {
    log.Println(err)
}

if resp.Ok != true {
    log.Println("Request did not return OK")
}

log.Println(resp)
