Rendering from Scratch with Rust

Implementing The Ray Tracer Challenge by James Buck in Rust 🦀

To dos:

• Fix scaling to modify current values instead of overwriting
• Make scaling change radius
• Add point() and vector() functions for better standardization
• Fix sphere origin so it can be set by either origin or translation. Currently somewhat broken
• Try calculating comps.over_point only for shadowed points
• Figure out what's wrong with rotation_z() function
