httpProxy exits when socks5proxy is set to nil

[komlevv]

Proxify version:

0.0.12

Current Behavior:

httpProxy exits when socks5proxy is set to nil

Expected Behavior:

expect http proxy to listen on default port :8888

Steps To Reproduce:

1. run >proxify.exe -sa ""
2. banner code runs
3. http server goroutine runs
4. proxify.exe process exits
   probably due to the goroutine lacking blocking code here

   proxify/proxy.go

   Lines 259 to 277 in a794db0

   	if p.httpProxy != nil {
   	p.httpProxy.TLSPassthroughFunc = func(req *http.Request) bool {
   	// if !stringsutil.ContainsAny(req.URL.Host, "avatars") {
   	// log.Printf("Skipped MITM for %v", req.URL.Host)
   	// return true
   	// }
   	return false
   	}
   	p.httpProxy.SetRequestModifier(p)
   	p.httpProxy.SetResponseModifier(p)
   	go func() {
   	l, err := net.Listen("tcp", p.options.ListenAddrHTTP)
   	if err != nil {
   	gologger.Fatal().Msgf("failed to setup listener got %v", err)
   	}
   	gologger.Fatal().Msgf("%v", p.httpProxy.Serve(l))
   	}()

Could probably fix with something like:

		httpProxyRun := func() {
			l, err := net.Listen("tcp", p.options.ListenAddrHTTP)
			if err != nil {
				gologger.Fatal().Msgf("failed to setup listener got %v", err)
			}
			gologger.Fatal().Msgf("%v", p.httpProxy.Serve(l))
		}
		if p.socks5proxy != nil {
			go httpProxyRun()
		} else {
			httpProxyRun()
		}
