FEAT: Using Row Objects in MacOS Cursor

[bewithgaurav]

Summary

This pull request refactors the Cursor class in mssql_python/cursor_mac.py to improve data handling by introducing a Row object for query results. The changes enhance type safety and make the interface more consistent by replacing raw sequences (e.g., tuples) with Row objects. Additionally, the implementation of fetchone, fetchmany, and fetchall methods has been updated to reflect this new design.

Refactoring for Improved Data Handling:

• Introduction of Row Object: Added an import for the Row class and updated the fetchone, fetchmany, and fetchall methods to return Row objects instead of raw sequences like tuples. This change improves type safety and encapsulates row data with metadata (mssql_python/cursor_mac.py, [1] [2] [3].

Method Updates:

• fetchone Method: Refactored to fetch raw data, check for no data, and return a Row object constructed with the row data and description.
• fetchmany Method: Updated to fetch a specified number of rows, validate input size, and return a list of Row objects.
• fetchall Method: Modified to fetch all remaining rows and return them as a list of Row objects.

• The module references ddbc_sql_const but it is not imported; this will cause a NameError. Please add the appropriate import for ddbc_sql_const.

        if ret == ddbc_sql_const.SQL_NO_DATA.value:

• The condition is inverted: it currently returns an empty list when rows are present and only converts when there is no data. It should be if ret == ddbc_sql_const.SQL_NO_DATA.value: to early-return on no data.

        if ret != ddbc_sql_const.SQL_NO_DATA.value:
