Include waarnemingen.be data

[jrhillae]

Probably including current waarnemingen.be data is very simple as I collected it in this file (the second sheet), mapped on iAsset data. Only management data is not yet present in this file, these are stored in separate Google sheets. Maybe I can combine these files and store a copy of the data (including management) in a third sheet within this file? This file is manually triggered to update daily for coordination.
