Generate a permutation of a given length having a given number of inversions

1	inv_vec(n, k, allow.dual = TRUE)

`n`	A positive integer.
`k`	A nonnegative integer at most `n`.
`allow.dual`	Logical; whether to allow exchanging large values of `k` for their duals to improve efficiency.

A permutation of n having k (non-arbitrary) inversions.
