Plot differentially expressed genes by Biotype

[grst]

Description of feature

I find it useful to assess the result of the DE analysis by plotting the number of differentially expressed genes by gene type. If the majority is not protein coding, it is usually a sign that something is not right.

Therefore, I suggest to add a plot like the following to the MultiQC report.

Gene types are typically available from the GTF file.

Sounds good, PRs gratefully received.

I think all the information for that should already be available in the R markdown document's parameters, especially where an Esembl GTF has been supplied as a workflow input (a tabular form of which is then passed to the markdown process).

Note that there's no MulitQC here- just the R markdown.
