refactor: bump version to 1.4.1 and update audio component API

Bumped the project version in `SoundFlow.csproj` to 1.4.1 and removed the
unneeded `STATEMENT.md` from the package.

Added comprehensive XML documentation to `SoundComponent.Process`, exposed
the method as public, and clarified its purpose and usage.

Updated the event raisers in `AudioEngine` to public for better external
accessibility and Made `CachedRenderEventArgs` protected so subclasses can reuse it.
