Fix zone checks

[JanSimek]

Currently, we check only 128 zones for zone violation, so this works on Integra 128, but other models support varying number of zones... 32, 64, 128, so we need to check zone number based on the model type.

for ($i = 0; $i < 16; $i++) {
    for ($b = 0; $b < 8; $b++) {
        if (pow(2, $b) & hexdec(bin2hex($raw[$i+3]))) { // 0xFE 0xFE 0x00 ..
            $number = 8 * $i + $b + 1;
            // TODO: self::PARTITION, self::OUTPUT, etc.
            $violated[$number] = $this->sendCommand("EE" . self::ZONEX . sprintf("%02s", dechex($number)));
        }
    }
}
