Marrmot get_value_as_xarray function only works on flux_out_Q

[SarahAlidoost]

Marrmot returns many variables as
('P', 'T', 'Ep', 'S(t)', 'par', 'sol_resnorm_tolerance', 'sol_resnorm_maxiter', 'flux_out_Q', 'flux_out_Ea', 'wb')

After model.update(), some variables like 'P' and 'T' are time series whereas others are one value. Therefore, the get_value_as_xarray function returns error as: cannot reshape array of size 1461 into shape (1,1).
