add 'return fig' to plot functions

[guigautier]

🚀 Feature
In visualization.py plot_subject and plot_volume is it possible de return the matplotlib fig ?

    'if output_path is not None:
        fig.savefig(output_path)
    if show:
        plt.show()
    return fig

Motivation
To send the figure to an experiment tracker.

thank you

I also use something like this in my code to send images to an experiment tracker (ClearML for example). Would be a nice addition to torchio
