Show plots

[mastoffel]

• this is a PR in response to a JOSS comment in the review thread
• plots now always show, whether run from a notebook or a terminal (previously one had to use plt.show in the terminal)
• plotting functions now use plt.show and return the fig object when run from a terminal, but don't use plt.show when run from a notebook, as that would cause double plotting
• added a function to determine the plot layout to avoid empty space when plotting multiple plots
• all tests needed monkeypatching to avoid having to manually close plotting windows while testing

LGTM! I've run the quick start example from the terminal and the plots showed as expected and the intro notebook still displays correctly as well.
