Sparks are not antialiased

[connyduck]

I really like this library but the spark animation looks somewhat blurry. After taking a screenshot I noticed that the drawn circles are not antialiased

This is probably solved by adding setAntiAlias(true) to the used Paints.
If you want I can try to provide a pull request.

Zoomed in screenshot of animation in progress.

Yeah.. it would be great if you can put up a pull request. I will release it on jitpack as soon as i merge it.
