Adapt combine_scorefiles to output information from scoring file headers

[smlmbrt]

combine_scorefiles already reads headers as a dictionary. The information extracted from the PGS Catalog style-header should be combined into a log/json file indexed by the scoring file accession that includes:

• [ ] Original genome build per scoring file
• [ ] Original number of variants
• [ ] Traits
• [ ] PGS Name
• [ ] Citation
• [ ] Which columns were used, variant sources, harmonisation status

Changes will need to be made to pgsc_calc to use metadata from the json rather than an API call. This will have the added benefit of not requiring internet access for any step of the pipeline after download_scorefiles. Changes needed:

• [ ] modules/local/score_report.nf
• [ ] bin/report.Rmd

@ens-lgil is this something you could take on?

Yes, I can have a look at it
