Implement new option smoother_redux, to allow fast smoother for very large models. It runs smoother only for state variables and computes the remaining ones ex-post
...
Contains improvements, in order to recover as much as possible static unobserved (filtered, smoothed, updated, k-step ahead), Variance, State_uncertainty, k-step ahead variances trying to map lagged states onto current ones using pinv(T). This has exceptions (namely lagged shocks which are ONLY used to recover static NON observed variables). this exception is also trapped.
For such extensions we can only recover smoothed variables starting from d+1. Variances CANNOT be recovered for such variables (the smoother gives ZERO.)

Bug fixes in fitered variances of smoother
...
- kalman_algo=1: kstep-ahead variances were WRONG, since Pf was initialized using P in PREVIOUS period
- kalman_algo=2: output argument for filtered varainces should be P1, not P (P are UPDATED variances, there).
For kalman_algo=2, also make a small factorization fix (compute P(:,:,t+1) before defining Pf, so to compute 1-step ahead variance only once)
