getForcePlates function returns an empty list.

[Tian-A-Tan]

This b3d file (and all the other files I tested) has force in many trials, but no GRF is returned by the function getForcePlates using the following code:

import nimblephysics as nimble

subject_path = '/AB06_split0.b3d'
subject = nimble.biomechanics.SubjectOnDisk(subject_path)
trial_protos = subject.getHeaderProto().getTrials()
for trial_ in trial_protos:
print(trial_.getForcePlates())

The above code follows that provided in AddBiomechanics repo post-processing code so it should be good.
