New order with multiple order-by columns

There are multiple use cases, where users have to emulate an order with multiple order-by columns as follows (which works due to stable sort):

X = order(target=X, by=3, ...)
X = order(target=X, by=2, ...)
X = order(target=X, by=1, ...)

This causes unnecessary overhead by sorting the dataset in the number of order-by columns. Hence, this task aims to support an order function that allows both scalar and matrix by parameters.
