Replaced the Progress Indicator in Daft Music that was originally the SwiftUI slider with a custom version that is written with CoreAnimation and is wrapped in a NSViewRepresentable. (Also, the progress is now fully animated)

CPU Usage went down while playing from 3-4% to 0%.

I'm not that person that wants Objective-C and AppKit back, but often I have to drop down to optimize for things and it's not that SwiftUI is often easier than straight Core Animation.
