Function find_orfs 

pub fn find_orfs(
    sequence: &DnaSeq,
    topology: Topology,
    table: u32,
    min_codons: usize,
    starts: StartPolicy,
) -> Result<OrfScan, TranslationError>

Six-frame search for complete ORFs: the longest ORF per stop codon (first start after the previous in-frame stop), at least min_codons amino acids. On circular molecules ORFs may wrap the origin but never exceed one molecule length; frames without any stop are not reported.
