Includes changes from #66 resolves #67

I get the following warning. It seems I didn't quite setup the cameras properly or something? If someone knows what's up please let me know or fix it.

2024-08-30T22:41:11.607981Z  WARN bevy_render::camera::camera: Camera order ambiguities detected for active cameras with the following priorities: {(1, Some(Window(NormalizedWindowRef(Entity { index: 0, generation: 1 }))))}. To fix this, ensure there is exactly one Camera entity spawned with a given order for a given RenderTarget. Ambiguities should be resolved because either (1) multiple active cameras were spawned accidentally, which will result in rendering multiple instances of the scene or (2) for cases where multiple active cameras is intentional, ambiguities could result in unpredictable render results.
