Expand description
TSV parser shared by every aligner backend.
Input: lines of tab-separated values with the 8 columns documented on
the crate root (qseqid pident evalue bitscore qcov stitle sstart send).
Blank lines and #-prefixed comments are skipped.
coverage_is_fraction = true indicates the source tool (e.g. mmseqs2)
reports qcov as a 0–1 fraction; we rescale to 0–100 for consistency.
