Approximates the Koopman operator `K` via the forward-backward DMD.
It is assumed that `K = sqrt(K₁*inv(K₂))`, where `K₁` is the approximation via forward and `K₂` via [DMDSVD](@ref). Based on [this paper](https://arxiv.org/pdf/1507.02264).

If `truncation` ∈ (0, 1) is given, the singular value decomposition is reduced to include only
entries bigger than `truncation*maximum(Σ)`. If `truncation` is an integer, the reduced SVD up to `truncation` is used for computation.
