Description of feature

Currently the pyDamage results are on a contig level, but it would be good to get a summary statistic in bin_summary.tsv so a user can evaluate which bins contain contigs with aDNA damage, when running with ancient DNA mode.

This will likely require parsing the pydamage results file, parsing ??? to get contigs in each bin, sorting the pydamage results per-contig results into the bins, making the median average across all columns (@alexhbnr 's approach), then adding this to the bin_summary table.
