/// Swaps two slices of a tensor.
/// # Arguments
/// * `tensor` - The input tensor.
/// * `slices1` - The first slice to swap.
/// * `slices2` - The second slice to swap.
/// # Returns
/// A new tensor with the specified slices swapped.
/// # Notes
/// This method will be useful for matrix factorization algorithms.
