#TODO the parent entrypoint.sh does something with a custom-extensions directory, review it and see if it does this unpacking for us
#TODO I still think ADD is best here since it can fetch from remote URLs, it sets us up to use artifactory
#TODO: https://github.com/nextgenhealthcare/connect-docker#additional-extensions - these can just be volume mounted or use `EXTENSIONS_DOWNLOAD` URL
