How to use react-native-obfuscating-transformer with multiple transformers/resolvers

I'm trying to add multiple resolvers and transformers using metro for my react native project, how do I combine them and obfuscate the code.

I am using metro-babel-transformer and react-native-svg-transformer

```
var upstreamTransformer = require("metro-babel-transformer");
var svgTransformer = require("react-native-svg-transformer");

module.exports.transform = function({ src, filename, options }) {
if (filename.endsWith(".svg")) {
return svgTransformer.transform({ src, filename, options });
} else {
return upstreamTransformer.transform({ src, filename, options });
}
};
```

My transformer.js look like this

从 issue 中的 transformer.js 示例开始，检查如何调用 metro-babel-transformer 和 react-native-svg-transformer。确定将这些 transformer 与混淆结合所需的文档化配置，然后根据 repository 中现有的文档或示例验证最终的用法。
