Changed the way of calculating speeds and turns (+ minor features)

The speed and turn will no longer be calculated using the calculated orientations but the tracked orientations will be used. The calculated orientations are flawed in the cases, that the entity stands still and there is noise in the tracking, or that the entity moves backwards which the calculated orientations could not handle.

• A new smooth rendering function was added "robofish-io-render".
• Black Auto-formatting as pre-commit hook
• Removed obstacle from examples (#8 (closed))
• Improved evaluation scripts (speeds, turns) with quantiles for histogram ranges.
