refactor!: make Emitter generic over offset instead of reader

Emitters should not have access to the reader at all.  Also the
current position of the reader, at the time an Emitted method is
called, very much depends on machine implementation details such
as if `Tokenizer::unread_char` is used. Having the Emitter
methods take offsets lets the machine take care of providing
the right offsets, as evidenced by the next commit.
