Add support for macOS

[DaemonLoki]

Currently, the library is only running on iOS and iPadOS.

Making it available for macOS as well would allow for more use-cases on the new platform. Due to the fact that it relies on SwiftUI for presentation and and CoreAnimation and SpriteKit for the effects, this should be possible in general.

There are some occurrences where it makes of e.g. UIColor which needs to be adapted but overall it's a possible thing to do and allows for way more flexibility in the usage.
