flutter_scene_soloud 0.2.0

• Widen the flutter_scene constraint to ^0.24.0.
• Move to flutter_soloud 5.1.2, which compiles the engine through a build hook and fetches prebuilt Ogg, Vorbis, Opus, and FLAC libraries for the target on first build, Linux arm64 included. Apps can instead link system packages, compile the codecs from source, or build without them through hooks.user_defines.flutter_soloud in their pubspec (see the README).
• The Linux bundle carries its codec libraries under their SONAMEs, so it loads on a machine without the distro codec packages.
• Web apps load assets/packages/flutter_soloud/web/init_soloud.js from index.html (renamed upstream).
• Requires Dart 3.11.
• Add SoloudAudioEngine.bufferSize (config key bufferSize) to start SoLoud with a smaller, lower-latency mix buffer.
• Fix mirrored, one-sided 3D panning when the listener pose was synced before any clip loaded and the camera then stayed still.
