Consistency check on free-surface evolution

This is optional and only applies to the time-implicit layered solver.

This checks that the free-surface position \(\eta\) obtained from the solution of the implicit time-integration matches the free-surface position \(\eta_p\) obtained by integration of the corresponding (barotropic) fluxes i.e.

\[ \partial_t\eta_p + \sum_l \nabla\cdot(\mathbf{hu})_l = 0 \]

This should be true to within the tolerance of the implicit solver.

The difference is stored in the deta field.
