Add a "NoConvertNull" param?

[sw-sw-sw-sw]

Encountering a specific use case where data is pulled from SQL as a DBNull. (actually the data is being aliased out of a SQL query rather than an data output from SQL). When converting the data output, we want to retain these null values as a null valued object of type "System.Object" [null], instead of "System.Object" [string].

Refer to line 329:

elseif ($v -isnot [String] ) {
                                #Other objects or null.
                                if ($null -ne $v) { $ws.Cells[$row, $ColumnIndex].Value = **$v.toString()** }
                            }

In our particular case the downstream system is expecting a null bit value (int32)... but that's irrelevant. It would just be nice to have an option to not convert null value data type and retain its original data type.
