NumericalTests fail ShearWave Test

CumulantK15Comp and CumulantK17CompChim both fail the ShearWave Tests. Could be related to #32

added gpu label

As long as the ShearWave tests fail I would like to disable them in the numerical test suite. Then we have at least not failing pipeline. With that we can at least see if we don't break any more things. @s.marcus can we do this together?
