BurpSuit的protobuf的解析支持

今天粗略看了burpsuit对protobuf的支持情况，对比了官方的protobuf插件和NCCGroup的插件，发现NCC的插件项目较为活跃，所以采用NCC的。

Installation

1. If Burp Suite is not already installed, download it from https://portswigger.net/burp/.
2. Download/Install Jython 2.7+ and configure Burp with the location. See https://portswigger.net/burp/documentation/desktop/extensions/installing-extensions
3. Clone this repository and then run git submodule update --init to install dependencies.
4. Within Burp, navigate to Extender -> Extensions and select "Add".
5. Set "Extension Type" to Python and select the extender.py file in the git repository.
6. Click Next and the extension should load.
7. Note: gRPC is supported, but you'll have to enable Burp's HTTP/2 support (under Project Options->HTTP). Also, currently only uncompressed gRPC payloads are supported. If the first byte of the payload is not 0x00, it's compressed and you'll have to modify the en/decoding code to account for that.

Installing Jython or JRuby

You need to install Jython or JRuby if you see a Download Jython or Download JRuby button next to the extension in the BApp Store. This enables extensions written in Python or Ruby to interact with Burp's legacy, Java-based Extender API.

To install Jython or JRuby:

1. Click the Download Jython or Download JRuby button.
2. Download the standalone JAR version of Jython or JRuby.
3. In Burp Suite, go to Extensions > Options.
4. Under Python Environment or Ruby Environment, click Select file.
5. Select the JAR file and click Open.
6. Go to Extensions > BApp Store. Notice that the Install button is now available for your extension.

       效果如下：

          因为protobuf只用数字来表明字段，所以这里用数字表示字段，应该也支持edit其中的字段，我还没尝试，后续需要的时候再测试。（不过似乎不支持自己上传.proto文件来解析）
