multiqc/proteinfold for a 'bulk report'

Description of feature

I've been working on a MultiQC module for proteinfold following #306, #312, etc

Draft PR here for feedback: MultiQC/pull/3462

This means a nice, lightweight, shareable HTML reports in core I've attached a couple to give a sense of what I mean.

multiqc_report_live-demo_group_relevant_cols.html
multiqc_report_Fos_Jun_homodimers.html

I'm planning to dev separately from the pipeline merging, so not dependant on release timeline. But, I've left a spot for RF2NA once #420 is addressed. Just needs to give the same simple .tsv formats from extract_metrics.py

You can find my dev code here: https://github.com/Australian-Structural-Biology-Computing/MultiQC/blob/9e5a4720929531d06d330be8e26fb47768e27615/multiqc/modules/proteinfold/proteinfold.py?

Conceptually this is meant to be for 'bulk' folding and screening, rather than the more detailed structure viewer from GENERATE_REPORT
