Fix transpiration regions

- rSW_CTL_obtain_inputs() now calls onSet_SW_SOILS() before onSet_SW_SIT_transp() -- this change was needed because onSet_SW_SIT_transp() requires soil depth information that is only available after it was obtained by onSet_SW_SOILS()

- see SOILWAT2 commit "Input specification of transpiration regions changed from layers to soil depth" (DrylandEcology/SOILWAT2@8c6432f)
