add code coverage CI to pipeline code (#71)

* add code coverage CI to pipeline code

* do coverage of pipeline not pyrenew

* don't hand in path

if already telling poetry path, maybe don't need to tell pytest a path

* remove extra model reference

* need some path?

* works locally, so it'll work here right?

* closer to model CI

* raw copy of working local code

* break long line

* go back to long line I guess
