Scripts for creating indic tileset

[planemad]

Ref #1

• Script augments a geojson with translated labels from Wikidata

[answerquest]

Just for clarity : what the script in this PR does is, from perspective of each individual place node:

• find wikidata tag if existing
• using that tag, pull in multilingual translations from wikidata
• add in those translations as name:xx tags. Where existing, replace. (pls confirm?)
• also do a bit of data cleaning

End result: if say a place node earlier didn't have multilingual tags in OSM but was linked to a wikidata id and that id happens to have the name in say 10 indian languages, now it will have them added in as if it's from OSM only, and so these language names can be picked up for the place in next stage.

Pls let me know if I got anything wrong here. And, nice! 👍
