Fio => YNAB transactions adapter

1. Copy config/env.example.php to config/env.php and fill necessary values
2. Run bin/run.php and enjoy!

Troubleshooting & sidenotes

• We are downloading transactions "From last downloaded transaction". If you need to manually adjust the breakpoint, you can run bin/reset-fio.php 1234 with transaction ID you want to return to.
• If you delete imported transactions from YNAB, it WON'T BE IMPORTED AGAIN - YNAB remember "import id" and reject them automatically (https://www.reddit.com/r/ynab/comments/7rrx16/help_how_to_reimport_deleted_transactions/). Solution could be modifying \App\Repository\YnabTargetRepository to use different import id (e.g. uniquid, md5 time or anything).
