File open encoding and date format about dkb2homebank

[hamvocke]

Thanks for the feedback! I assume you downloaded your CSV file from the new banking portal, not the old one? What account type do you have (does it say "DKB Cash" or "Girokonto" in the UI)?

DKB seems to have changed quite a bit around their CSV export lately, and depending on the account type you've got and the portal you're using to download the CSV file, you might be getting mixed results.

You're totally correct, the new portal seems to generate CSV files with utf-8-sig encoding and the date format is slightly different. I tried to make those tweaks for the --giro flag and removed the entire auto-detection mechanism (since we can't reasonably maintain it with all these variations, really), hoping that this helps moving forward.

It's a Girokonto and I did download it from their new portal. Thanks again for your work. I just got started using homebank and without your script I would probably have given up. It's wild to me that pulling my transactions is this hard, I would have expected them to provide an API and instead we get a CSV download with changing format.

Heads-up: with the latest commit, I removed the --cash, --visa, and --giro flags from the script. It should now be capable of automatically detecting the input CSV file and do the right thing out of the box.
