Pulsator

With just three lines—instantiate, add to layer, and start—you can create smooth pulse animations, as demonstrated in the README example.

Offers control over pulse count, radius, color, duration, and easing functions via properties like `numPulse` and `animationDuration`, allowing fine-tuned visual effects.

Works seamlessly on both iOS and macOS with the same API, reducing the need for platform-specific code, as noted in the README's macOS support section.

Can be integrated into Objective-C projects using bridging headers, making it accessible for mixed-language development, though the Swift version is preferred.
