Break up long reads into 150mers to enable long read data for variant calling

[zachary-foster]

A collaborator has tested a lot of methods for variant calling with long read data and determined that breaking up reads into 150mers and using graphtyper works the best of the methods tested. This would be a easy way to accept long reads into the variant calling portion of the pipeline.

Here is an example command for doing this:
cat $infile | seqkit sliding -W 150 -s 150 -o ${strain}_nano150.fastq.gz

This has been implemented in the dev branch
