Test NetCDF with demand_priority

[visr]

For #2604, address this TODO:

https://github.com/Deltares/Ribasim/pull/2604/files#diff-e25c8aa097712a2c5032f50517e8c8f741fe2e90328a22542e6b7e9e016ccf92

To be able to do this I need to wait for a NetCDF exported from FEWS with multiple Basins. This should be available in a week or two.
