Parallelizing

TODO: before this we do combining iterators with .zip() and then go over destructuring into tuples there

• this is a stretch exercise

• Brief intro to rayon

• par_iter()

• into_par_iter()

• with_min_len()

• Objective is to calculate the pairwise distances between two vectors of points super fast

• we want to use .zip() to combine the two vectors

• this would require using rand to create a vector of random numbers
