feat: side panel controls

[jim-at-stink]

Switching over to using the GameRenderer React component instead of a legacy render function, to match the approach and some naming used in the go-v2 visualizer.

Initially fix issues where the game steps weren't updating due to some stuff with the resize observer in the handling of the legacy approach, this has the added benefit of correctly wrapping the React renderer in the various playback controls so they now show correctly when in side-panel mode.

@develra I've switched things over here and in go-v2 to pass in a React component to the ReplayAdapter instead of the legacy function, can you take a quick look and let me know if thist is how you'd anticipated this React component approach to be done? Thanks!

Looks fine to me as long as it works - let me know if you need adjustments to ReplayAdapter / createReplayVisualizer for anything.

Is this all commented out now? If so maybe remove if you don't think you'll need it in the future.
