BREAKING behavior LiveWireTool2D
Reworked/fixed LiveWireTool2D. Now correctly works on 4D images
with static or dynamic segmentations.
Changed behavior to have a clearer/simpler UX. Now, unconfirmed
life wire contours are WYSIWYG. They will painted to the time step/ slice
visible when confirmed. No matter in which time step the creation of
the live wire was started/done.
