Mode arrays with LVCNR waveforms
It was uncovered in a surrogate waveform review that some LVCNR waveforms may be generating arrays of 0s instead of raising an error when a missing mode is requested. See for example, https://git.ligo.org/waveforms/reviews/NRHybSur3dq8/wikis/NRHybSur3dq8_vs_RIT#gatech.
This might be coming from code near here: https://git.ligo.org/lscsoft/lalsuite/blob/master/lalsimulation/lib/LALSimIMRNRWaveforms.c#L839
There don't seem to be checks for missing modes.
