This issue mainly deals with adding output grids that are aggregated over time. Let's discuss methods of viewing in #148.

Just wanted to note that rather than using `DataArray`, we probably should use `NullableArray` instead. `DataFrames` master has already switched over, `NullableArray` should work better with Julia's type system.

@Alexander-Barth thanks for showing NCDatasets, it wasn't on my radar before. We should indeed link to it in our readme as well. Regarding `netcdf_c.jl`, it is currently auto generated, followed...

@Yujie-W was the issue resolved? I don't know what kind of feature this would be, isn't UInt16 (NC_USHORT) supported by default? https://www.unidata.ucar.edu/software/netcdf/docs/data_type.html

> Assuming this is configuring and building the binary libnetcdf, there should be a file libnetcdf.settings generated somewhere. The binaries are downloaded from here: https://github.com/JuliaBinaryWrappers/NetCDF_jll.jl/releases/tag/NetCDF-v400.702.400%2B0 This includes a libnetcdf.settings with...

Isn't this already supported? https://deltares.github.io/Wflow.jl/dev/user_guide/step2_settings_file/#Modify-parameters ```toml [input.vertical.precipitation] netcdf.variable.name = "P" scale = 1.5 offset = 0.5 ```

Ah indeed, that cannot be done using the modify parameters feature. Nice that you've been able to make it work this way. Do you think this will be used regularly?...

> With the custom run loop, it means that we run from Julia right? In principle yes. Though if executables are needed it is also possible create a branch on...

Note that there are also 3 BMI tests that need to get updated for the new number of variables; https://github.com/Deltares/Wflow.jl/runs/7631174183?check_suite_focus=true#step:6:142

> what would be a good location to store these custom run functions, also in relation to building an exe (TeamCity)? For building an exe the easiest is just to...
