BMv3: Velocity vectors in flood-vars

In BMv3, flow direction could not be derived from FLOOD dataset.

In model.json, within the HYDRAULICS block, it is possible to track flood-variables with the statement:

"FLOOD": {
    "tracking_timestep": 300.0
}

Then the results.h5 container contains a dataset at RESULTS/CellsAll/FloodVar with flood arrival time, the maximum water depth, flow velocity and specific discharge.

The per time-step data (RESULTS/CellsAll/HydState) on the other hand contains water surface elevation, specific discharge in x direction, qx  and specific discharge in y direction, qy. From the later two it is possible to calculate flow-direction and draw some nice flow arrows.

So the feature request is to add qx and qy to the flood dataset.

Thanks, Michel
