- refactor of the Http client

Changes:

Http-client settings in configure method

```
    TikTokLive.newClient("X")
                .configure(liveClientSettings ->
                {
                   var httpSetting = liveClientSettings.getHttpSettings();
                    httpSetting.setTimeout(Duration.ofSeconds(12));
                });
```

`TikTokLive.requests()` Easy and quick way of making
http request to tiktok
```
    var giftsResponse =TikTokLive.request.fetchGiftsData();
 ```

 Removed:
     TikTokLive.isLiveOnline(String hostName);
     TikTokLive.isHostNameValidAsync(String hostName);

     instead you can use
     ```
     TikTokLive.requests().fetchLiveUserData("Mike").getUserStatus()
     ```
