Add TRANSACTION_PAYLOAD_EVENT and handle unknown event types gracefully

MySQL 8.0.20 introduced TRANSACTION_PAYLOAD_EVENT (type 39) for binlog
transaction compression. This event type is missing from ConstEventType,
causing a ValueError on MySQL 8.0.20+ / 8.4 servers.

Changes:
- Add TRANSACTION_PAYLOAD_EVENT = 39 to ConstEventType enum
- Use tryFrom() instead of from() in EventInfo to gracefully handle
  any unrecognized event types instead of crashing
