Is your feature request related to a problem or challenge?

calculate_range issues two get_opts requests to find the beginning and the end newlines for a given file range, and once these newlines are found, there's another get_opts request for the specific range

Describe the solution you'd like

Basically reuse the AlignedBoundaryStream (#20823 ) implementation for CSV.
