Update scv plugin

[jesper-friis]

The csv plugin now gives a lot of errors of the form:

csv.py:202: FutureWarning: Series.__getitem__ treating keys as positions is deprecated. In a future version, integer keys
will always be treated as labels (consistent with DataFrame behavior). To access a value by position, use `ser.iloc[pos]`

and

csv.py:10: DeprecationWarning: 
Pyarrow will become a required dependency of pandas in the next major release of pandas (pandas 3.0),
(to allow more performant data types, such as the Arrow string type, and better interoperability with other libraries)
but was not found to be installed on your system.
If this would cause problems for you,
please provide us feedback at https://github.com/pandas-dev/pandas/issues/54466
    
  QUOTE_MINIMAL, QUOTE_ALL, QUOTE_NONNUMERIC, QUOTE_NONE, \

Update the plugin to get rid of these errors.

Also consider to add more user-friendly options.
