[BUG] The EPI DKG seems to be missing a few geonames nodes

[liunelson]

I used this endpoint to try to find the curie for locations in the United States.

However, no result was returned for these terms:Vermont, Maine, West Virginia, Wyoming - they can be found here though
https://www.geonames.org/search.html?q=wyoming&country=US

Similarly, the term Delaware only returns a result with the prefix ncit, not with geonames, even though it exists.

So this seems to occur because we filter out all cities that have a population under 100,000. And for those states you listed, none of the cities in those states in the dataset we use have a population over 100,000. And because of the way we add geoterms currently, we don't add those states as geonames nodes in the EPI DKG. This logic isn't the best and we should add all countries and states and filter only on the city level. I'll work on this.
