Rarity Script Missing

[five31]

First, love this build. Thank you so much.

Second, Looks like the rarity script is missing from the latest build? Running npm run rarity returns the following:

npm ERR! Missing script: "rarity"
npm ERR!
npm ERR! To see a list of scripts, run:
npm ERR! npm run

I've tried the node utils/rarityData.js and that's pretty great. However, I'm really looking to us the rarity to generate that csv.

Any advice?
