* Improve the level sending mechanism in the game.

Instead of sending a request for each chunk one by one, and in sequence, send all the level data in one block.

I know this is not the best solution since we are working with UDP here, but it's way faster than loading the level chunk by chunk. In a blink of an eye, the level has already loaded.
