Getting 'encoding' error

```
$./easyBankcsv2qif.py ../EASYBANK_Umsatzliste_20211128_1122.csv 
Traceback (most recent call last):
  File "./easyBankcsv2qif.py", line 324, in <module>
    instream = open(args.file, mode='r', encoding=args.encfrom)
TypeError: 'encoding' is an invalid keyword argument for this function

```

Same goes with a csv file as param
