Describe the feature

Currently the player/target cast bars are removed instantly when a cast is finished/interrupted (accounting for the time-to-hold). I would like to be able to choose an animation, such as 'fade out'.

I suppose this may naturally extend to also an animation that occurs when the cast starts, such that it 'fades in'.

Describe the implementation

An option on the cast bar that allows you to choose a predefined animation that occurs when the cast starts/finishes, with a duration input that controls the amount of time it takes for the animation to complete.

I'll add Fade In & Fade Out animations for now. Adding multiple types is a bigger undertaking so you should open another Issue for that.
