This moves responsibility for tracking animations and switching to next/previous animations out of the various paintables and into a single location
All animations have an initial render delay of 0ms for their initial frame.

I was able to have a chat with @vanvoljg offline. This PR was on track to merge and didn't have any blockers, so I think we can reopen it. |

Here, animation loading, state, and management are pulled out of
RGBMatrix.Engineand into theXebowapplication. This separates a few concerns to where theEngineonly has to deal with rendering,RGBMatrix.Animationhandles functions related to animations themselves, andXebowhandles creating the list of animations, initializing animations, switching animations, and persisting config modifications in memory.This should make it easier to introduce other application controlling logic such as animation activation/deactivation, configuration persistence between reboots, and eventually runtime discovery/installation of animations (which are currently hard-coded into the animation module).
This PR also fixes the black frame on live view creation, and removes the 0-ms
render_inthat was returned by all animations on callingnew/2. Animations which need to delay the render of their first frame could set the first frame to black, have an internal state that determines how long to wait, and check that state in itsrender/2callback functions.addresses part of #49, but leaves open a bunch of questions aboutruntime discovery of animations, enabling/disabling, etc.
