Model integration tests

[savente93]

Issue addressed

Fixes #940

Explanation

• For the mesh, it needs to have some data attached for the checks to work and I couldn't figure out another way of adding some data to it except for just using

  mesh_model.mesh.add_2d_data_from_rasterdataset(
      "vito", grid_name="mesh1", resampling_method="mode"
  )

  Probably there is a faster way, if anyone can think of one please either just push to the branch or let me know

• There are three tests that I have left skiped. All are basically to do with me not knowing how to add proper data to them, so I will need some help here, though it should be extremely easy to make them pass once I know what kind of data is appropriate.

As stated in the description there are three tests that I left skipped due to needing a bit of help, but I'm opening it up for review anyway, so that the gross of the changes can get reviewed.
