Raise ValueError if StringOutput.write() gets data of unsupported type

... instead of returning/storing an "informal string representation".

Replaces the test for the "odt" writers" with binary output in
`core.publish_programmatically()` with a generic alternative
(that also catches the case of the "null" writer instead of writing
the string "None").
