Realize an alternative grid cartogram of 1913 Italian elections?

[severo]

https://github.com/severo/data-grid-cartograms/tree/main/countries/it/collegi/1913_Guerzoni does not fully reflect the 45° orientation of the original map.

We could propose an alternative one, where we turn the map by 45° to the right, transcribe it to CSV, and then make it clear in the README that the grid cartogram should be oriented 45° left when rendering.

(rotated with https://www.imgonline.com.ua/eng/contact.php, thanks for the maintainer)

Note that the angle is not exactly 45° and differs slightly in mainland Italy, Sicily, Sardinia, or even in the bottom left part of mainland Italy to better follow the coastline.
