Add a way to reset the velocity of a SkeletonModification2DJiggle

[Zoomulator]

I've been animating a character's hair with the new skeleton jiggle modifications.
It's well-behaved while animating smooth character movement, but I have to occasionally do a "hard" move, or teleport, over a longer distance which causes the jiggle modification to calculate a very high velocity and completely "spaz out".

Looking through the docs and the source https://github.com/godotengine/godot/blob/master/scene/resources/skeleton_modification_2d_jiggle.cpp I can't find a way to avoid this happening.

How would you go about working around this?

A few ideas comes to mind:

1. Add an option for a distance, over which the modifier will interpret the change in position as a teleport and will adjust to the new position before calculating velocity again. I think this offers some out-of-the-box sanity for all users.
2. Add a max speed option. This wouldn't eliminate the jerk on a teleport, but it would mitigate the spazzing.
3. Add a reset function that may be called after you've changed the position that causes velocities and relative orientations of the affected bones to be reset.
