• What kind of change does this PR introduce?:
  This removes the logging config from the init. Logging config is normally done by the end user, not the package itself ? I see logging stuff in clisops, so I'm guessing the config that was set here was overrided anyway in most cases ?

In my case, this unwanted logging configuration was making my console spit way too much stuff that I don't need. More generally, our usecase of clisops is in workflows using xscen, where we take care of the logging configuration ourselves.

I also updated the environment.yml file that was missing a few dependencies present in setup.py.

• Does this PR introduce a breaking change?:
  I guess not. If yes, the removed line are exactly what I user would need to add to their code to retrieve the previous behaviour.
