Function parse_data_records_with_header 

pub const fn parse_data_records_with_header<'a>(
    data: &'a [u8],
    header: &'a LongTplHeader,

Parses DIF/VIF data records using context from a long transport header.

Header context is needed for data encodings whose interpretation depends on transport-layer metadata, such as two-digit years.
