Disable 3rf's default tone mapping

[khdlr]

By default, react-three-fiber applies some tone mapping to the scene, causing our terrain map textures to look too bright and washed out. This PR fixes that by disabling the tone mapping.

TODO:

• This also affects the visuals of the rendered buildings. Should we adjust the building / simulation colours? I'd consider making the non-simulation buildings (beige ones) a bit brighter/less saturated.

Yes, I also think less saturated looks better.
