Ray Tracing the Next Week

This is my attempt at Ray Tracing the Next Week book by Peter Shirley.

On x86_64 target, It'll try to use AVX2. If you get build errors, Try commenting the simd_vec3 import in src/types/mod.rs. I tried changing the cfg attribute to, all(target_arch = "x86_64", target_feature = "avx2") but it keeps reporting that avx2 feature is disabled on my machine?

Without AVX2, The final scene takes ~33 seconds to render at a certain setting and with AVX2 the same scene takes ~23.5 seconds.
