Daniel 8685688698 installable package (#9)
* turn repo into installable package (pip install -e .)

* add hatchling build packend

* call it pytest-abra

* add pytest entrypoint, so that it gets loaded automatically if installed (and pytest is run)

* make fixtures optional, so that pytest can still be used in other context

* add cli script -> you can now directly run "pytest-abra" in console
