Using Turing.jl for an ARIMA 1,1,0 model.

Is there a way to extract the AR,MA (if i used 1,1,1) coefficients from the fitted model?

```plaintext
@model ARIMA110(x) = begin
    T = length(x)
    μ ~ Uniform(-10, 10)
    ϕ ~ Uniform(-1, 1)
    for t in 3:T
        val = μ + # Drift term.
              x[t-1] + # ARIMA(0,1,0) portion.
              ϕ * (x[t-1] - x[t-2]) # ARIMA(1,0,0) portion.
        x[t] ~ Normal(val, 1)
    end
end

out_arima = ARIMA110(x)

```

Thanks,
