Add tests for WaveActiveMin

[KungFuDonkey]

Adds tests for WaveActiveMin, based on the WaveActiveMax tests in #429

I generated the results using a python script, but I cannot figure out how to run the tests. Any guidance on that would help

The tests look reasonable to me. I've kicked them to the CI to run.

It complains about WaveActiveMin not existing, which is currently true as the WaveActiveMin PR is not in. Did I miss something that should make this expectedly fail?
