The Replay module ignores tokens

Currently, the Replay module ignores tokens. This prevents external tools such as KaTie to perform queries involving tokens (e.g. jonathan-laurent/KaTie#21 from @hmedina ). The simplest fix would be to add a field tokens: (string * Nbr.t) array to the state type and ensure that rule applications correctly update this field.
