Function section_records_resolved 

pub fn section_records_resolved(
    s: &SectionRef<'_>,
    after: Lsn,
    fetch: &mut dyn FnMut(&OffloadRef) -> Result<Vec<u8>>,
) -> Result<Vec<(Lsn, RecordBuf)>, ResolveError>

section_records for a section that may hold references, keeping only the records after after (the others are neither decoded nor read back): fetch reads the bytes a reference names (they are checked here).
