Bug in Optimization Examples

[ASU-ScopeX-Lab]

None of the optimization examples works, as it wrongly multiplies design_region in the objective

epsr = epsr_min + (epsr_max-epsr_min)*operator_proj(_rho, beta=beta, eta=eta) * design_region
simulation.eps_r = epsr

should be

epsr = epsr_min + (epsr_max-epsr_min)*operator_proj(_rho, beta=beta, eta=eta)
simulation.eps_r = epsr

otherwise there is no waveguide ports in simulation.....
