Sets the first H2O species to have a constant relative humidity (RH).

The water vapour saturation pressure is obtained by water_p_eq_agenda and the setytings in this agenda determines if the RH is e.g. defined with respect to liquid, or a combination of liquid and ice.

Only the first H2O species is modified.

The default value of vmr_threshold aims at avoiding changing VMRs above the tropopause.
