WARNING /scratch/jfrost/cset-workflow-env/lib/python3.12/site-packages/CSET/operators/plot.py:140: RuntimeWarning: More than 20 figures have been opened. Figures created through the pyplot interface (matplotlib.pyplot.figure) are retained until explicitly closed and may consume too much memory. (To control this warning, see the rcParam figure.max_open_warning). Consider using matplotlib.pyplot.close().

So it looks like we just need to close them after saving.

Close figures after saving, and refactor plotting code
6cfef8b 
Refactors the plotting code to use the explicit (object-oriented)
matplotlib API. Figures are explicitly closed, preventing memory
leaking. Also added a super-title to the postage stamp plots, so
the diagnostic title is there too.

Fixes #481
