Update of the objective function 33 and 34 for et, twsa and q
twsa and et is averaged to monthly timesteps, standarized with classified standard score and then MAE is used.
In 33 for q the BoxCox of MAE is used, while in 34 for q the error measure is 1-KGE.
For that purpose some new subroutines are added, and used in other subroutines, as well.
