Ray Tracing In One Weekend - in Rust

This is my implementation of the Ray Tracing in One Weekend series. I had been thinking about making my own Rust port for this series for a long time now, so here it is!

I tried to keep the code as close to the book as possible with only a few minor deviations in type and variable names. All of the CPU renderer code is self-contained but I decided to use the following third-party crates for a few things that are implemented directly in the book:

images to convert sRGB to the stored image format (in this case PPM)
rand and rand_distr to sample from uniform distributions. I made use of the UnitSphere and UnitDisc utilities instead of implementing rejection sampling myself (which wouldn't be hard but I chose to explore the crate for learning purposes).

You can build and run the code by executing the following inside the cpu-renderer directory:

cargo run --release

cargo run --release -- --help will output the following:

Usage: cpu-renderer [-p <samples-per-pixel>] [-m <max-bounces>] [-s <scene>] [-w <width>] [-h <height>]

Ray Tracing In One Weekend: CPU renderer

Options:
  -p, --samples-per-pixel
                      number of samples per pixel
  -m, --max-bounces maximum number of ray bounces per traced path
  -s, --scene       the scene to render ("simple" or "cover")
  -w, --width       image width
  -h, --height      image height
  --help            display usage information
