Unicast Network Sim Update 1

This update adds a prototype web assembly build of the game to allow players to play the game directly in the browser.

Known bugs / problems:

• Mute button does not work.
• Exiting the game ends the render loop but does not stop the music.
• Music keeps playing when the game is not focused.
• Game is not mobile-friendly (requires keyboard inputs and does not resize dynamically).

Expect (some) these bugs to be resolved over the coming versions.
