Nextflow review @bobturneruk ep11, new content

[ggrimes]

I don't think this episode introduces very much new content. An option would be to separate out the new content (e.g. "Metrics and Reports") and set up the episode as an extended exercise for learners - end the content prior to https://carpentries-incubator.github.io/workflows-nextflow/11-Simple_Rna-Seq_pipeline.html#define-the-pipeline-parameters and set an exercise to produce the code in script6.nf? Or maybe the extensive recap is intentional.
