Binary column errors out with InvalidCastException

[JeffHenson]

When trying to read a binary column, sometimes it errors out when accessing it from the DbDataReader. I say sometimes because when the declaredColumnTypes variable in the NuoDbDataReader is not set it doesn't error out.

If it helps, here's a small program that reproduces the issue: https://gist.github.com/JeffHenson/17b95e5b12f5428ebe26618a06901d97

This was tested with commit e5823eb.

The reason for the failure is that, when the declaredColumnTypes are available, the value returned for a column is converted into that type. For the VARBINARY column, this type is BLOB, that is mapped into a .Net type of System.Object. But the returned byte[] value can't be converted into a generic Object, so the exception is thrown. We'll look into fixing this mapping.

Is there a suggested workaround for this?
