WebAssembly build

[elliott-wen]

Hi, thanks for sharing this cool project. It would be cool if we have a webassembly version of robocode so that people can watch a robocode game session in a browser. :D

I could offer some help on that. I guess this should be relatively easy, since we just need to fetch the game state and render it as is. I could implement it either in Rust or C++ with sdl.

Let me know what you think. :D
