change Separator in class-aal-exporter-csv.php

Hello,

i need to change the Separator in class-aal-exporter-csv.php > public function write ($data, $columns) {}

There is
fputcsv( $fp, $columns );
and
fputcsv( $fp, $encoded_row );

It must be
fputcsv( $fp, $columns, $separator = “;” );
and
fputcsv( $fp, $encoded_row, $separator = “;” );

It would be nice to change the Separator in the PlugIn-Settings of WP-Admin, then i don’t need to change it by myself every official update.
