Implement a "prerun step" using ProtInfo

[CatChenal]

• Using dataset structure from bench_setup, iterate over each pdb folder in runs/:
• Collate the 2 dicts from each run, e.g:

for pdb_dir in bench_dir/runs:
    cd pdb_dir
     d1, d2 = protinfo.info.collect_info(pdb, args)
     prerun_data.append((d1, d2))
     cd ../
...

# collate report lines
# save report in `bench_dir`

• Notes:
  • Report creation (aka, "prerun") is integral to bench_setup;
  • To display/serve it to the user, the 'launch right away' flag (--launch) must not be used in the bench_setup command.
