Addresses an issue where CauseDis would hang when loading the smoking example after the latest DataShaper update. This was caused by changes that default DS table loading to not apply types unless a codebook is present, so all columns were being assigned a nature of "categorical nominal" and therefore getting a onehot applied - which created massive amounts of new columns and hung the app.
Adds a codebook to the example table, so it is correctly typed
