Function slerp_normalized 

fn slerp_normalized(from: Vec3<f32>, to: Vec3<f32>, factor: f32) -> Vec3<f32>

Begone ye NaN’s Slerp two Vec3s skipping the slerp if their directions are very close This avoids a case where veks slerp produces NaN’s Additionally, it avoids unnecessary calculations if they are near identical Assumes from and to are normalized and returns a normalized vector
