Unhandled Exceptions on Validation

[bluec]

Been using this in production for a while for postcode validation and we see all sorts of unhandled exceptions when validating postcodes.

Looking at the \JustSteveKing\LaravelPostcodes\Service\PostcodeService::validate method:

  public function validate(string $postcode, bool $preValidate = false): bool
  {
      if ($preValidate) {
          return !!preg_match(config('postcodes.regex.postcode'), $postcode);
      }
  
      return $this->getResponse("postcodes/$postcode/validate");
  }

Parsing the various status and error responses would be tiresome, so as a simple fix would it be better if the request were wrapped in a try/catch block and return false on any exception....

  public function validate(string $postcode, bool $preValidate = false): bool
  {
      if ($preValidate) {
          return !!preg_match(config('postcodes.regex.postcode'), $postcode);
      }

      try {
          return $this->getResponse("postcodes/$postcode/validate");
      } catch (GuzzleException $e) {
          return false;
      }
  }

I've tried this and it works for me. Happy to do a PR if this is an acceptable solution.
