Is it possible to test LambdaFunctionURL lambdas with aws-lambda-rie ?

I have a 2 lambdas:
* One that take a `CloudWatchEvent` as the second argument of the `Handle()`function
* One that take a `LambdaFunctionURLRequest`as the second argument of the `Handle()`function

I'm able to successfully test with `aws-lambda-rie`the first Lambda but not the second one

Even with a quite naive handler:
```
func Handle(ctx context.Context, request events.LambdaFunctionURLRequest) error {
log.Printf("body: %s", request.RawPath)
return nil
}
```

Is it possible to test this "new" kind of lambdas using `aws-lambda-runtime` ? Am I doing something wrong ?

首先，使用 Go Handle 函式透過 aws-lambda-rie 重現該請求，並比較 CloudWatchEvent 與 LambdaFunctionURLRequest 兩種情況。該 issue 沒有指定任何 repository 檔案或測試；完成意味著確認是否支援 LambdaFunctionURLRequest，並記錄或實作所需的行為。
