Fix stream info pagination and add test for empty stream list

[koushamad]

Fix: streams_info Method Only Returns First Page of Streams #591

Observed behavior The method only returns the first page of streams (up to 256 streams) and does not paginate through the remaining streams.

Expected behavior This merge request adds a test to verify that the streams_info method correctly handles offsets, ensuring proper pagination when retrieving streams. Additionally, it implements the necessary changes to the streams_info method to support pagination.

• Added a test to verify the streams_info method handles offsets correctly.
• Implemented pagination in the streams_info method to support retrieving streams with an offset.
• Implemented streams_info_iterator method to retrieve a list of streams as an iterator.
• Created StreamsListIterator class to handle iteration over the list of streams.
