Add configurable parallel/sequential pagination with parallel parameter

- Add `parallel: bool = True` parameter to control pagination strategy
- Parallel mode (default): Fetches all pages in parallel for maximum speed
- Sequential mode: Fetches pages one-by-one with early termination checks
- Early termination stops pagination when time-based filters indicate no more matches
- Useful for rate limiting and narrow time windows
- Simplified pagination logic by removing hybrid first-page pre-check
- Updated README with usage example and parameter documentation
- Version bump to 0.8.4
- All 54 tests passing
