// Our incremental JSON parser (simplified only to use strings and arrays)
// while iterator result != done keep using .next(moreSrc) or .next(null) if you are done providing data
// while the iterator is not done it will return the state of the iterator

// the iterator is seeking more data to get a valid value
// call .next(str) to provide it more data

// the iterator has a valid result and will return a result if you provide .next(null)
// this is not automatic, due to numbers and potentially invalid trailing characters after an expected end
