v0.0.2 of flutter_oneshot_player

Low-latency one-shot audio sample player for Flutter. Native AVAudioEngine on iOS/macOS, Oboe on Android. Changelog excerpt: ### Bug fixes - **Swift Package Manager product name corrected.**The library product in darwin/Package.swiftwas named flutter_oneshot_player(snake_case). Flutter's build system derives the expected SPM product name in kebab-case (flutter-oneshot-player), so the mismatch caused Flutter to skip SPM and fall back to CocoaPods silently. Renamed to flutter-oneshot-player; apps built with Flutter 3.27+ will now use SPM automatically for both iOS and macOS.
