Audio setup and config setup

[AnnLe4869]

I have setup some very basic audio that can play audio and explosion sound periodically and jump sound on keyboard event. Will look into how to do the partial sound I also setup the config such that we can read all config from inside a single json file. like this

std::cout << "My name is " << SetupParser::getValue("name") << std::endl;

right now I put some example setup in the common/setup.json but I image we can do more with this.

thanks for setting up audio and config! this looks good.

I can approve this but looks like some merging is necessary

It works on my machine! I'll approve it once I understand the cmake changes.
