@biology/seqtk: Process FASTA/FASTQ sequences

Seqtk is a fast and lightweight tool for processing sequences in the
FASTA or FASTQ format. It seamlessly parses both FASTA and FASTQ files
which can also be optionally compressed by gzip.  It performs basic
file conversions and edits much like standard Unix tools do with text
files.
