        return "0x" . strtoupper(dechex($byte));
    }, $byte_arr)) . PHP_EOL;

echo "Byte dec map = " . implode(" ", $byte_arr) . PHP_EOL;

Known issues

• Not support tags. 6 major type (in future)
• Not support 16 and 32 floats encoding (maybe in future)
• All floats will be serialized only as IEEE 754 Double-Precision Float (64 bits follow)
• Encode does't support indefinite-length values.
