New module: Proteinfold (protein structure AI inference programs - v2 metrics)

[keiran-rowell-unsw]

Test data for a MultiQC module for nf-core/proteinfold (draft PR here)

Covers the main metrics in simple .tsv format. See the EBI guide for the description of confidence scores common to all AI protein structure inference codes:

• MSA - Multiple Sequence Alignment (for depth of homologues sequences)
• pLDDT - predicted Local Distance Difference Test (spatial error per amino acid residue position)
• pTM - predicted Template Modelling (global structure accuracy)
• ipTM - interface score (predicting relative positional accuracy of the subunits)
• PAE - [excluded from lightweight MultiQC report] predicted aligned error (matrix of relative positional error between every pair of residues)
