Add reference fasta for demo data

[kimte1]

Ask away!

Hi!

I ran v1.3.1 on test1.fastq.gz in wf-clone-validation-demo (downloaded using the README instructions) just to see what the HTML output would look like for a "positive control." I'm wondering if a full_reference and insert_reference could also be added to the demo folder.

Thanks!

Thanks for this @kimte1 - good idea.

We'll add an example of using references to the demo data.
