"The column mapping from SourceColumn 'FullName' failed because the DataColumn 'FullName' is a computed column."

Hello,

I think I found an issue in Protobuf-net-data project.
I tried to signup on GitHub to add this issue, but i receive an error, so I decide to send you a mail.

I have attached a sample project where you can see the error about I am talking.
The problem is that serialization of a dataset does not skip the computed columns, and when I try to load the dataset, it gave me the error "The column mapping from SourceColumn 'FullName' failed because the DataColumn 'FullName' is a computed column."

The example (car table) has columns Maker, Model, and computed FullName (expression = Maker+Model). The error message is actually being thrown by a strongly-typed DataSet.Load(), but protobuf-net-data should not have serialized the FullName column.
