Function transpose_small 

pub unsafe fn transpose_small<T: Copy>(
    width: usize,
    height: usize,
    input: &[T],
    output: &mut [T],
)

Given an array of size width * height, representing a flattened 2D array, transpose the rows and columns of that 2D array into the output benchmarking shows that loop tiling isn’t effective for small arrays (in the range of 50x50 or smaller)
