Fix NameError in stochastic_volatility.ipynb
Show progress bar with parallel sampling

This commit enables a progress bar when using `psample`. This done by

only a single job, the progress of other jobs should usually be very
similar (and it is better than having no feedback on the state of the
sampler).

This closes #374.
