feat: add DVD channel

[willow-bohlen]

Description

Adds a DVD channel, for all your logo-bouncing needs!
Each donation spawns a new logo. When a logo hits a corner, it will cycle through a rainbow of colors (and likely cause much twitch chat hype). One logo also spawns when the channel is first opened.

If too much motion is a concern, logo speed can be adjusted. Can also make the colors less saturated if it's too much right now.

Hey,
I think it might be more engaging if a donation would not spawn a logo but instead it would spawn a text showing the donation amount which is then moving across the screen. Similarly, I think it might be fun to have the donation total move and change color as well. That way, something would still be happening on screen even if no donations are coming in.

What do you think about that?

I started working on something like that before realizing that you have already created a PR for a DVD logo screen. If you're interested in my idea, I think we could collaborate on this.

For reference: This is what it looks like right now. Spawning the donation amount is not implemented yet, but it should be quite easy to add.

(Please don't mind the visual artifacts. That's a problem with my recording software which I can't fix right now.)

@Rick-T Hi! I thought about that, but I fear that it might become a little too busy with all of the numbers on screen, especially if the donation total is also bouncing around. Maybe instead, donation amount could correspond to the logo size?

Also, to note: one logo spawns when the channel opens, so it won't be an empty screen at any point.
