2023 Release 3 - Multiple input CSV formats

Shout out to Botond and the MTG players at KISS :)

Changelog:

• Added support for multiple inventory csv formats!
  • Deckbox
  • Deckstats
  • Manabox
  • Moxfield
  • MtgGoldfish
  • Tappedout
    • This one was tricky, as they don't note both faces of a double-faced card. I solved it with a scryfall search for every double-faced card which happens at startup time.
  • Anything where the following headers are present:
    • for card quantity either one of ["count", "amount", "quantity", "qty"]
    • for card name either one of ["name", "card_name", "card"]
    • (The trick noted under Tappedout works for any csv if you have that limitation)
