@spec many(Chrysopoeia.parser(i, o, e), [{:count, non_neg_integer()}]) ::
  Chrysopoeia.parser(i, [o], e)

A combinator. Applies parser on the input as many times as it can.

Must match at least opts[count] times (defaults to zero).

@spec many_until(Chrysopoeia.parser(i, o, e1), Chrysopoeia.parser(i, any(), any())) ::
  Chrysopoeia.parser(i, [o], e1 | any())

A combinator. Applies parser on the input until until matches.

Unlike Multi.many, if parser fails before until is found, the parser errors out.
