Add NWM Ponded Depth (NGWPC-9175)

[idtodd]

This change adds as a CFE NWM_PONDED_DEPTH calculation to LASAM. The output variable name is lowercase for LASAM for consistency with LASAM's variables and to prevent multiple BMIs from sharing the same output variable names (something that can cause problems in Multi_Bmi_Formulations.

CFE calculates the ponded runoff as the sum of the giuh runoff queue during it's Update method. LASAM will now replicate this method.

Additions

• bmi_unit_conversion::volrunoff_guih_ponded_m double value added for storing the calculation.
• BmiLGAR::Update computes the ponded value and assigns it.

Removals

Changes

• BmiLGAR::serialize accounts for this value.
• BmiLGAR::output_var_names has its size increased and "nwm_ponded_depth" added.
• BmiLGAR variables methods GetVarGrid, GetVarUnits, GetVarLocation, and GetValuePtr updated to look for "nwm_ponded_depth".

Screenshots

Notes

• The default value of bmi_unit_conversion::volrunoff_guih_ponded_m is not defined in creation or initialization from config file, just like all other bmi_unit_conversion values.
