Feature Request: Additional Animation Parameters for Shine ChangeEffect

[mergesort]

I hope this is the right place to ask for more fine tuning, but either way thank you very much for the library!

I was trying to use the .shine ChangeEffect for animating a button tap, but the animation duration is too long for my use case. I see that other ChangeEffect's have parameters to try and fine tune the animation, and was hoping that it would be possible to add additional parameters to .shine. While I only want the timing to be faster, I could see the edges being exposed as a parameter being useful to others as well, but I'll leave that to your best discretion.

Happy to provide any more information that may be useful, and thank you again!
