dotween Allow DOTweenAnimation to specify starting value

Hello,

We consider this to be a missing feature. DOTweenAnimation should allow (optionally) to specify what value it should start from instead of the current value left in the editor. Here is a simple use case:

I have a white button in a normal state.
It has a DOTweenAnimation that when enabled it should flash the button from dark orange to light orange.
DOTweenAnimation is used so the artist can set whatever he likes animation without touching the code.

At the moment it seems impossible to set the starting value (no matter TO/FROM) of the tween. It will always flash from white to orange. There are ways to go around this, but it would be simpler if DOTweenAnimation supported this.

We ended up extending it, adding "Start Value" option. It hooks up right before tween creation and sets the specified value, so the DOTween created finds this as initial value. It is kind of a hack indeed. Had to fix the preview as well to restore it on stop.
