[FEATURE] Automatically adding lighting in Plotly scenes

Description

With #412, Plotly became a very decent option for rendering large 3D scenes. However, Plotly doesn't add lighting to its scenes by default, which makes it difficult to discern edges.

While we can manually add custom lighting, it would be great to have lighting added to every scene by default.

One possible contribution would be:

• Finding good defaults for lighting parameters and position.
• Check if we can apply the same lighting to all meshes in a scene. Currently, we need to pass the lighting when drawing the mesh, so two different meshes could have different lighting (don't know if that's a real issue).

Hi, I’d like to work on this issue—can you assign it to me?

Hi @Asachdeva001, I'm not assigning people to this kind of issues. Just open a PR and I will review it :-) Note that someone else also started a PR (see #414).
