Datasource
The driver accepts three types of sources of data:
Uniform Resource Locator (URL) - a Web address to perform HTTP request.
Plain text file with TopoJSON data - identified from the file extension .json or .topojson
Text passed directly and encoded in Topo JSON
Starting with GDAL 2.3, the URL/filename/text might be prefixed with
TopoJSON: to avoid any ambiguity with other drivers. Alternatively, starting
with GDAL 3.10, specifying the -if TopoJSON option to command line utilities
accepting it, or TopoJSON as the only value of the papszAllowedDrivers of
GDALOpenEx(), also forces the driver to recognize the passed
URL/filename/text.
