Shouldn't this unittest be under the beamformer/ folder? Also, shouldn't it be
named nonlinear_beamformer_unittest, since it only test the
nonlinear_beamformer? On top of that, shouldn't it then be combined with the
unittest?

Absolutely! That is also what I wrote in the CL review invite. I will make that
change.
