Adding custom sensor data

[superseppl]

Dear Team,

thanks for the project. I would like to ask with respect to adding different kind of data. I have a set of IMUs (~8) that I attach to the body on different segments (left foot, right foot, left shank, right shank, left thigh, right thigh, sacrum, sternum) with x-axis up, z-axis forward, y-axis left. I was able to read them, define a skeleton (see skeleton.py, here with right wrist and left wrist) and run the InertialPoseFusionFilter but somehow in the visualizer it only shows all the points on the x-axis (see image). I tried to setup the default_seg_angles as well as the default_raw_imus_manual_alignment to align them with the NWU frame (x-axis forward / y-axis left / z-axis up). Am I missing something? Thanks in advance.
