// We need this because we want offsets of the original parser unchanged when
// we're working with a new parser in CreatedTimeStamp().
// deepCopyParser creates a copy of a parser without re-using the slices' original memory addresses.
// The function `CreatedTimestamp()` uses a copy of the parser to "peek" at _created lines that might be several lines ahead, without changing the state of the original parser.
//
// Additionally, deepCopyParser switches `skipCT` from false to true, because this new parser needs to return _created lines.
