Enhance relay testing and event handling

- Updated TestRelay to include a wait mechanism for relay readiness, improving test reliability.
- Refactored startTestRelay to return the assigned port, allowing dynamic port assignment.
- Added timestamp validation in HandleEvent to reject events with timestamps more than one hour in the future.
- Introduced channels for handling OK and COUNT messages in the Client struct, improving message processing.
- Updated tests to reflect changes in event timestamp handling and increased wait times for event processing.
- Bumped version to v0.20.6 to reflect these enhancements.
