Add attribution for zoom & pan animation code ported over from Recordly

Pull Request Template

Description

Adds attribution to Recordly from animation code ported from Recordly to OpenScreen

Motivation

I only found out today that Recordly wasn't attributed for the zoom animation code, and originally, I was fine with it, but as OpenScreen grows I think the origins of the zoom animations should be set clear, especially as I spent days working on them.

I don't wish ill towards OpenScreen, just something small I wanted to set straight :)

Poem

🐰 A rabbit's whisper, soft and light,
Attribution shines, so clear and bright,
From Recordly's lands, the code did roam,
Now credited well, it's found a home! ✨
