Generate a hypercube of the optimal balance of plant

[TimSlendebroek]

The balance of plant an internal optimization is very slow (50 % of the total ActorWholeFacility)

For the stationary solution we should make a database of results as there are only 3 inputs and a cycle type for now::

cycletype :: Symbol
breeder_heat_load :: Real
divertor_heat_load :: Real
wall_heat_load :: Real

@orso82 had the idea to make a hypercube and then just interpolate on the optimzed result to speed this up to almost nothing

@jacksonharvey Do you think this makes sense?

[jacksonharvey]

Ya that makes sense, should be fairly easy to add.
