3.0.4.1

Fixed an issue where Session.subscribe threw an exception when userName and password were not provided.
Fixed an issue where incorrect parsing of cluster redirection information could cause prolonged reconnection time.
Fixed a memory leak that could occur when using the PROTOCOL_ARROW protocol for data communication.

Add SimpleDBConnectionPool to create and manage connection pools.
Add support in TableAppender, TableUpserter, PartitionedTableAppender, and MultithreadedTableWriter for inserting data into stream tables in Orca.
Add tryReconnectNums parameter to MultithreadedTableWriter to set reconnection attempts.
Add usePublicName parameter to DBConnectionPool and MultithreadedTableWriter to support using node publicName as the connection address in a cluster environment.

Optimize log output.
Optimize the reconnection mechanism to avoid holding the GIL in certain cases.
Optimize Session connection information updates to timely detect node changes.
Optimize script execution restrictions: when fetchSize is specified, other scripts cannot be executed until the current data fetch is completed.

Fixed an issue where the cluster cannot be successfully connected when specifying tryReconnectNums=1.
