remove lambda phage reads from a fastq file

 NanoLyse is a tool for rapid removal of contaminant DNA, using the
 Minimap2 aligner through the mappy Python binding. A typical application
 would be the removal of the lambda phage control DNA fragment supplied
 by ONT, for which the reference sequence is included in the package.
 However, this approach may lead to unwanted loss of reads from regions
 highly homologous to the lambda phage genome.
