Remove debugging and analytics for production

[Headonpillow]

Remove un-needed debugging and analytics tests in final production-ready container

This issue is to be implemented at later stages.

Examples of checks to remove in .R scripts:

  # Basic checks
  # They are expected to be provided by Snakemake
  # The checks are mostly needed when running the script interactively for debugging
  if (is.null(samples_file)) {
    stop("Missing required input: 'samples'")
  }
  if (any(vapply(list(track_out, qc_out, seqtab_out), is.null, logical(1)))) {
    stop("Missing required outputs: expect names 'track','qc','seqtab'.")
  }
