Phaser.Time.Timeline: Loop functionality (including events and callbacks)

[micsun-al]

Phaser: 3.60.0

Timeline could use a loop functionality with associated properties, events, and callbacks.

I was going to type in a bunch of text and information about how loops work, but uhhh, here's the old timeline :D

One workaround is using (Phaser.Time.Clock).delayedCall and setting the duration to the timeline's max duration, and then starting the timeline over as needed in the callback.
