#### PR Summary
This pull request adds functions to fetch data one by one and in batches from DDBC bindings.
- `mssql_python/pybind/ddbc_bindings.cpp`: Added `FetchMany_wrap` and `FetchOne_wrap` functions for fetching multiple and single rows of data, respectively.
- `mssql_python/testing_ddbc_bindings.py`: Introduced `fetch_data_onebyone` and `fetch_data_many` functions for testing the new fetch capabilities.
- Updated debug print statements to use `std::cout` for consistency.

This pull request introduces several enhancements and fixes to the FetchMany_wrap function in the ddbc_bindings.cpp file. The changes ensure proper handling and binding of various SQL data types, including character, wide character, integer, floating-point, timestamp, and binary types. Additionally, the PR includes a SQL Server query to create a table with all these types and insert sample data for testing.

Changes Made
Data Type Handling and Binding:

Added proper handling and binding for the following SQL data types:
SQL_CHAR
SQL_VARCHAR
SQL_LONGVARCHAR
SQL_WCHAR
SQL_WVARCHAR
SQL_WLONGVARCHAR
SQL_INTEGER
SQL_SMALLINT
SQL_REAL
SQL_FLOAT
SQL_DECIMAL
SQL_DOUBLE
SQL_TIMESTAMP
SQL_DATETIME
SQL_BIGINT
SQL_TYPE_DATE
SQL_TIME
SQL_GUID
SQL_BINARY
SQL_VARBINARY
SQL_LONGVARBINARY
Buffer Resizing and Binding:

Resized buffers appropriately based on the fetch size and column size.
Used SQLBindCol_ptr to bind columns to the respective buffers.
Data Fetching and Conversion:

Implemented data fetching and conversion logic for each data type.
Ensured proper null-termination for wide character data.
Added debug statements to verify data fetching and conversion.
SQL Server Table Creation and Data Insertion:

Provided a SQL Server query to create a table (TestTable) with columns of various data types.
Inserted 5 rows of sample data into the table for testing purposes.
Detailed Code Changes
ddbc_bindings.cpp:

Updated the FetchMany_wrap function to handle and bind various SQL data types.
Added buffer resizing and binding logic for each data type.
Implemented data fetching and conversion logic, including proper null-termination for wide character data.
