Please add this filter

After this on line 125:
do_action('pre_acui_import_single_user', $headers, $data );
Please add a filter like:
$data = apply_filters('pre_acui_import_single_user_data', $data, $headers);

This allows code to modify the imported field. For example, I want to turn comma-separated fields into an array. It’s easy with this filter:

function fixSpecialties($data, $headers) {
    $key = array_search('specialties', $headers);
    if ($key !== false) {
        $specialties = explode(',',$data[$key]);
        $data[$key] = array_filter(array_map('trim', $specialties));
    }
    return $data;
}
add_filter('pre_acui_import_single_user_data', 'fixSpecialties', 10, 2);

Thanks.
