Description

For the LHM, we could get away with only supporting the columns which are required for that specific model.

For example, for ScalingFactors, we either support excluding the package, or including it with data for all variables, being required or optional. This has the problem that depth of the perched water table is an optional variable, and needs to be NOT specified to turn it off.

For IBRAHYM, I'm now running into the fact that scaling factors are provided, but the depth perched water table is turned off. The MetaSWAP IO manual mentions this is an optional column.

Research direction

Start by tracing how MetaSWAP ScalingFactors columns are read and validated, comparing the LHM and IBRAHYM cases described in the issue. Confirm how optional variables such as perched-water-table depth are represented when disabled, and consider the work complete when required columns still work while optional columns can be omitted or turned off.
