Parametrize tests for detectors based on list of fixtures.

[jwlodek]

A lot of the tests used for ADAravis, ADKinetix etc. should be run for all detector classes. Ideally, we should make a module test_detectors that has a list of fixture names for all the different detector fixtures, then runs tests for each one.
