Title: BUG: SQLGetData called with SQL_C_BINARY type errors for SQL_NUMERIC/DECI

Fix failure in GetDataString for SQL_NUMERIC/SQL_DECIMAL
This came up when adding an output converter for SQL_NUMERIC/SQL_DECIMAL-- resulted in failure in SQLGetData in PostgreSQL ODBC and also the Netezza ODBC drivers. Haven't tested any others.

Generally speaking, when querying large datasets, conversion to Decimal and converting back to float (especially for putting data in NumPy arrays) is a major bottleneck. Can you think of any strategies to get around this?

I'd be happy to add a test case or two for this if you'd like.

I also note you have CRLF issues in the pyodbc repo, assume you're developing on Windows?
