[Question for Improvement]: replace new and delete/[] by the Smart Pointers

Hey two guys ,

I am using this repo in my project and I observe very often that the Web part does not react any more.
So it is like the server is gone in a way but the chip (here the ESP8266) shows connected to the wifi.
I saw the release infos and looked into the code.

So I came to the idea, would it not be a good thing to replace the new and delete by the Smart pointers like std::unique_ptr and it friends to prevent from memory leakage in future.
Memory leakage is difficult to detect, so I think it would be a good point.

What do you mean about this?
