plot W2W results

[dargueso]

Added script and image to visualize before and after w2w.
Added information to README on outputs and this figure.

Thanks for having a look at this!

The image as a png does not work well with dark mode:

we can either create two plots (one for light, the other for dark mode) or just make it a jpg, leaving out the transparent background.

For the plot script I am wondering if we can do this in a loop, to save on copy pasta code. I'll have a look at that and maybe come up with a suggestion.

I tried merging the options that are applied to each plot a bit. Unfortunately I wasn't able to run the code, because I can't install cartopy. They require Proj>=8.0.0, but my focal only comes with 7.2.1. They don't provide any wheels on PyPi either, so I tried building a wheel in a docker container in ubuntu jammy, where you can get a newer version of libproj-dev. This worked, but the shared object file of libproj.so is obviously not included in the wheel (like for instance ecmwflibs does), copying it over also doesn't work, because libproj.so (statically) links to other shared objects, that are not on focal.
Only option I can see would be building libproj from source...

Maybe you can have one last look and check if the notebook runs, then I can clean up the commits a little and it's good to go. Thanks for your great work on this 👍

I tried to run it but I get the following error:

AttributeError: 'LineCollection' object has no property 'right_labels'

when saving the figure. For some reason gridlines doesn't like receiving that option through: ax1.gridlines(**ax_options).

If I try gl1.right_labels=False. It works fine. The same for top_labels.

huh, that's annoying - I changed it back and was also able to get things up and running using docker. So this should all work now!

I'll have one last look myself, please also do so. Then I think it's ready and I can squash and merge it.

Tested. Good to go! 🟢
