Working with unions

[ghost]

I'm fine playing around with structs, but when I add the following to the thrift file:

union Identity {
  1: string email;
  2: string ssn;
}

I can't instantiate the Identity union. It feels like I should be able to use:

(thrift/->thrift (map->Identity {:ssn "21582"}))

but this throws the error "Not an optional field: email"

Does the library currently support unions? If so, I'd be happy to add documentation to the readme.

I have to look into it again, but IIRC it was hard to distinguish between unions and structs via reflection (which thrift-clj relies on), since they are using the same type ID.

But yes, this was on the initial road map, I just never got around to it. That said, contributions are welcome. :)
