dashes-to-dashes goes "serverless"

jq is a known tool nowadays, with lots of uses everywhere in the industry. 

Today I just replaced dashes-to-dashes api that is hosted in heroku, (it is a single endpoint that did a json transformation) to a jq script that can live in a github, and travis can be the one that runs and self publishes itself, putting the json in the github page of the repo, so it's fast, statically served, and requires no heroku dinos to keep it running.

If something, I learnt about extracting keys from a hash in jq
