split into microservices instead

so before we had several different helpers in their own repo, however it was hard to keep them updated and consistent, so we merged them all into the current repo

however, if one service goes down, then they all go down - and - if we need to deploy one service, we have to deploy everything

instead, we should move to a microservice infrastructure now that now.sh is a thing, so still have a mono repo, but have each service deployed and tested individually, with the main helper as a proxy service to the individual services

cloud functions is actually the new way to go
