example for gallery for pgf backend and integration with latex

[anirudhkrishnan2718]

Hi,

Is there any interest in an example showing how to use the pgf backend to save figures that can be inserted into a latex file

• Uses lualatex to avoid the limitations of matplotlib's mathtext parser
• Guarantees font matching with latex document by ensuring the same fonts are used in the latex preamble and the ultraplot pgf preamble
• Optionally save the figure as a png that can be loaded for display in a Jupyter notebook.

This is a very specific use case, so I am not sure if there will be interest in creating this example.

Bit outside the scope of UltraPlot as this is handled through matplotlib. Simplest example would just be

importultraplotasupltfig, ax=uplt.subplots()
fig.save("test.pgf")

Then import that in latex.
