Template entry point. This function takes up to two unnamed positional parameters:
1 = coordinate string typically from a call to Wikidata like this: {{#property:P625|from=Q...}}
2 = coordinate parameters; see Template:Coord

Also takes the named parameters |display=, |format=, |name=, |notes= which it passes on to {{coord}}

Reformats the Wikidata coordinate string into unnamed parameters for {{coord}}

{{#invoke:WikidataCoord|main|{{#property:P625|from={{{1}}}}}|{{{2}}}|display={{{display}}}|format={{{format}}}|name={{{name}}}|notes={{{notes}}}}}
