Why bevy_math doesn't have Triangle3d struct?

[busf4ctor]

I often find myself needing to work with 3D triangles in one of my personal projects. However, there's no bevy_math::primitives::Triangle3d. I believe a dedicated Triangle3d struct could be useful.

Advantages:

• Clarity: More explicit representation of a common geometric primitive.
• Convenience: Provide methods tailored to triangles (area, normals, etc.).

Workarounds

I am using the bevy_math::primitives::polygon. It sacrifices clarity and convenience.

I'm willing to contribute the implementation. Are there any downsides or reasons this might not be a good fit for bevy_math?
