Given a position point returns a precomputed value used for the flux computation via HyperbolicSystem::flux_contribution().

The default implementation of this function simply returns a zero value. In case of the The Shallow Water Equations we precompute the bathymetry. In case of LinearTransport we precompute the advection field.

Reimplemented from ryujin::InitialState< dim, Number, state_type, 1 >.
