The fun continues with `Invalid time format`. ```python now = datetime.datetime.now().replace(microsecond=0) curs.executemany("select ?", [(now,), (now,)]) ``` ``` Traceback (most recent call last): File "C:\Python36\lib\site-packages\turbodbc\exceptions.py", line 31, in wrapper return f(*args,...

Is the turbodbc element size used for both memory allocations and ODBC Column Size? Perhaps they need to be separated, that is feed [this value](https://github.com/blue-yonder/turbodbc/blob/1.0.4/cpp/cpp_odbc/Library/src/level2/level1_connector.cpp#L238) from a separate path.

The driver "ODBC Driver 13 for SQL Server" does not have these problems, it also performs better in my testing. "SQL Server" is included in windows installations, so it is...

For Python 3 that definitely makes sense. On Python 2 I don't have any strong opinion. Since turbodbc does not currently use unicode, it is probably best to keep everything...
