This will ensure that BaM is adding the correct number of derived parameters 'b' in the MCMC file (BaM's behavior is to compute derived parameters only for observed combinations of VAR_indices).
This should be fairly straightforward if a single 'period' column is used for all VAR parameters, but we need to decide how to handle the case where the user requests distinct periods for distinct VAR parameters.
