3.30.0

• Query session attach stream handles NodeShutdown and SessionShutdown session hints: on NodeShutdown the session's node connection is pessimized and the session is retired, on SessionShutdown the session is retired without touching the node
• Honor the max_bytes parameter in topic reader receive_batch/receive_batch_with_tx (previously accepted but silently ignored); add max_bytes to the async reader as well
• Support the timezone-carrying types TzDate, TzDatetime and TzTimestamp in query results and parameters (reading them previously raised AttributeError)
• Drop support for Python 3.8 and 3.9; the minimum supported version is now Python 3.10
• Accept native datetime.datetime values for Datetime and Datetime64 query parameters (previously only integer seconds since the epoch were accepted)
