feat: replay archived games, gamestate hash verification (#195)

create endpoint to load archived game. when joining game client first
checks if the game is active, if not it requests the game archive from
the server. the archive is sent to LocalServer to replay the game
locally. Every 10 ticks a hash is stored on the archive, and during
replay the LocalServer verifies this hash.
