feat: Improve playback with RingBuffer and EventScheduler

- Use a RingBuffer that has 4x buffer size with preallocated memory to
  handle playback data write and read. The previous implementation
  allocate and deallocate data array constantly during callback, which
  is inefficient
- Use EventScheduler to provide the same functionality of scheduling
  play event with onset (delay time)
- version 0.5.3
