When using SQLServerBulkCopy to import a BigDecimal into a Numeric column the scale isn't checked.

If the column metadata is defined as a Decimal(10, 4) and then new BigDecimal("1").setScale(2, RoundingMode.HALF_UP) is passed the table will end up with a value of 0.01 instead of 1.0

I think it would be safer if the IOBuffer.writeBigDecimal was passed bulkScale by the SQLServerBulkCopy.writeColumnToTdsWriter method and then threw an exception when the bigDecimalVal.scale() differed from bulkScale
