Possibility to sync animation across skeletonizer

[NikHomann]

I would love to have the possibility to sync the animation across different skeletonizers on one view.
Right now, if I use individual skeletonizer it works, but the animation looks a bit off.

Using several individual skeletonizers has two advantages in my opinion.
First, this would allow me to show the widgets as soon as their state is loaded and keep show the loading animation only for part of the page that needs longer. Secondly, it would allow me to keep the state locally in the individual widgets, making my code cleaner, because I would not have to have a "root" skeletonizer knowing about all the state of the individual widgets on this view.

I do not know if anybody else has this issue, but for me it would make this great package even better.
