Support array of strings

[untoreh]

In the url parameters you can specify multiple text strings (or q it's the same) so that instead of splitting a long string into substrings and call each time a translation, call it only once with the array of substrings.

[untoreh]

So in order to support arrays...
getResponse

    if (!is_string($string) && !is_array($string)) {
        throw new InvalidArgumentException("Invalid argument provided");
    }

In this function should be specified also the guzzle aggregator (duplicateAggregator), or maybe in the options passed to the translate class? Right now I am hard coding it into guzzle because I did not find the correct method to edit it from the http client.

then just a couple of functions, the one to detect the languagues and the one to get the correct array format...
instanceTranslate

   $array_flag = is_array($string);
   if($array_flag){
            foreach ($responseArray[0] as $itemArray) {
              foreach($itemArray as $item){
                 if (is_string($item)) {
                    $detectedLanguages[] = $item;
                }
            }
        }
        }else{
            foreach ($responseArray as $item) {
                if (is_string($item)) {
                  $detectedLanguages[] = $item;
                }
            }
        }
        if($array_flag){
            $carry = array();
            foreach($responseArray[0] as $item ){
                $carry[] = $item[0][0][0];
            }
            return $carry;
        }else{
        return array_reduce($responseArray[0], function($carry, $item) {
            $carry .= $item[0];
            return $carry;
        });
        }

that's it
