To add example for time dependent coupling to a bath

[neversakura]

You are right, the documentation on this part is a little bit unclear. Currently, there are two objects TimeDepedentCoupling and TimeDependentCouplings. You will need to define each time-dependent coupling operator first and combine them into a TimeDepependentCouplings object.

For your example, the code should be

Δ = 0.1
H = DenseHamiltonian([(s)->2*s-1, (s)->1.0], [σz, Δ * σx], unit=:ħ)
η = 0.001
fc = 4 * 2 * π
T = 20
bath = Ohmic(η, fc, T)
coupling = TimeDependentCoupling([(s)->s], [σz], unit=:ħ)
couplings = TimeDependentCouplings(coupling)
u0 = PauliVec[3][1]
annealing = Annealing(H, u0, coupling=couplings, bath=bath)

I will add some additional tutorials/documentation on this.

That was a really quick reply! Thanks. It seems pretty straightforward.
