feat: add animation duration option

## Description Adds an optional `animationDuration` property to the `createSwapy()` method. If `animationDuration` is specified, the default animation duration will be overridden with the user-specified value. If `animationDuration` is not specified, the animation defaults to the duration set by the `getAnimateConfig()` method. ## Example usage ```typescript createSwapy(container, { animationDuration: 180 // Set swap animation duration to 180ms }) ```
