E.g. write_csv(parties, here(stamp_date("data/output/parties.csv")))

If today's date were 2025-03-17 would write the file to "[project root]/data/output/2025_03_17_parties.csv"

Robust to if user puts

• write_csv(parties, here(stamp_date("data/output/parties.csv")))
• write_csv(parties, stamp_date(here("data/output/parties.csv")))
• write_csv(parties, here("data/output/", stamp_date(parties.csv")))
