When keying rotation in Spine Editor. Spine chooses the closest rotation to lerp/tween between keys.
Eg. if key at 340° - 20° it will rotate 340 -> 360/0 -> 20.
In Defold keys 340° -> 20° will rotate backwards ( 340° -> 180° -> 20 ° ).
This will give the visual bug shown in the gif where the cogs should rotate smoothly in one direction all the time. Defold should at least in spine.play_animation respect the Spine Editor behaviour (without making it different in normal rotation property animations in go.animate or gui.animate)
