Flipping body axis between head and taill while drosophila tracking

Hey,

this is difficult to determine from the images alone. But,

• posture_direction_smoothing should probably be disabled for now. this is more a bandate than a solution. the reason the posture may be flipping back and forth is that the shape does not really have a "pointy end". so determining tail/head would be inconsistent.
• outline_smooth_step should be default
• less smoothing in general would be better, and then use outline_approximate instead (e.g. 2 or 3) since it allows for one end to be smaller
• you could try to have lower threshold when converting so you get the wings (in case they have any), which would make the shape less symmetrical / one end pointier, and then approximate

If this does not help, then it's likely a data-problem. Meaning the shapes are just not pointy enough to be automatically determined. I think it should though!
