#19874 new enhancement

Add read/write support for TopoJSON format

Description

I would suggest that adding option to load and write into TopoJSON files would be useful.

One reason is that the format seems to be very close to OSM data structure in sense that objects reuse the same polygon segments and it also makes the file smaller: ​https://github.com/topojson/topojson-specification

Another is that Python GeoPandas package will soon add support for the format and it would be nice to move data between JOSM and GeoPandas this way: ​https://github.com/geopandas/geopandas/issues/1387
