For example, the Hubbard bloq example `hamiltonian_simulation_by_gqsp._hubbard_time_evolution_by_gqsp().controlled().t_complexity()` gives call graph errors like `DecomposeTypeError: Could not build call graph for C[C[Ry(2.214297435588181)]]: Could not build call graph for C[Ry(2.214297435588181)]: Ry(2.214297435588181) is atomic`.

It looks like adding controlled Toffoli now lets `.t_complexity()` work when controlling just the GQSP part of the Hamiltonian simulation, as in `hamiltonian_simulation_by_gqsp._hubbard_time_evolution_by_gqsp().gqsp.controlled().t_complexity()`. However, controlling the entire Hamiltonian simulation still...
