Allow plotID to run from command line
contrary to #53 (closed) following &6 we eventually want to be able to call plotID from outside of a python script. use this issue to collect necessary changes:
- a script-file needs to be handed over with publish
- programming environment / dependencies need to be handed over in another way (this needs to support multiple ways, link to a docker repository, a docker-compose yaml?, VM images, along with some readme)
