Adding N'ko Wordlist

Hi @m4rc1e! I was just about to start trying this out and I see that there isn't an N'ko wordlist. Wondering if one could be created. Fortunately, there is a tool that is being used to collect N'ko words primarily from N'ko news sites. Without an account you can get 1000 of the most frequent words from here. [N'ko Wordlist](https://app.sketchengine.eu/#wordlist?corpname=preloaded%2Fnko&tab=basic&wlminfreq=0&wlicase=0&include_nonwords=1&itemsPerPage=500&showresults=1&cols=%5B%22frq%22%5D) There is also some n-gram data is that is useful too. [N'ko N-gram](https://app.sketchengine.eu/#ngrams?corpname=preloaded%2Fnko&tab=basic&ngrams_n=2&ngrams_max_n=6&showresults=1&itemsPerPage=500&kngrams=0&cols=%5B%22frq%22%5D)

Would this be doable from this list? It does look like there are some English words that have been pulled in that need to be scrubbed out. Thanks.
