GeoLayout plugin update with new map projection(s)

GeoLayout is a great plugin for lots of people working in the field of cartography (in geography, history, social sciences, etc.). It would be great to update it with some recent map projections. It seems that it's all about translating the projection formula into GeoLayout.java

I see two projections that could be immediately useful:

### "Bertin 1953"
This is a great map projection for everything related to 20th century history and geography, because it's slightly organized around the North pole. Recently, a team of geographers made a comprehensive work around this projection, presented [here](https://visionscarto.net/bertin-projection-1953). At the bottom of the page, you find the [formula](https://github.com/d3/d3-geo-projection/blob/main/src/bertin.js) in a d3.js version.

### No distortion at all
For very zoomed-in maps (country level, city level), as well as for schematic maps, it would be very useful to be able to plot the nodes on a strict x/y referential, like a scatter plot or a simple grid. No formula, then.
