Add lalsimulation waveform-generation python tests
Description
This patch adds test_waveform_generation.py to /lalsimulation/test/python, which attempts to generate a waveform for every approximant using one or more of the XLALSimInspiralTD, XLALSimInspiralFD, XLALSimInspiralChooseTDWaveform, and XLALSimInspiralChooseFDWaveform.
The approximants are handled in parametrised groups, the idea being to sanity check the code by generating a non-zero waveform, and not test much else. All tests run with zero spin, and zero eccentricity, with the following exceptions:
-
HGImrihass1z = 0.6 -
EccentricFDandEccentricTDhaveecc = 0.1
Additionally, because the CI doesn't have access to lalsuite-extra, or lvcnr-lfs, approximants requiring external data are skipped.
ATOW, the following cases are failing:
| Approximant | Function(s) | m1,m2 | Error |
|---|---|---|---|

I am happy to be told that the input parameters are wrong for one or more of these tests.
